Product Description

EIO Glass Kids Cup (8oz). Totally BPA free. Unmatched Versatility. Environmentally Friendly. Starting with genuine, durable canning jars, EIO's unique design offers the only spill-resistant toddler training cup designed for convenience and health benefits. Available in: Orange, Green, or Purple. The Kids Cup is a spout-free, valve-free cup made without BPA, Phthalates and PVC, and is designed to transition young children properly from bottles to real glass dinnerware. Sippy cup spouts and valves necessitate a bottle-like sucking motion, but EIO's unique cap promotes correct sipping, quickly and with less mess!

Give them confidence. Give yourself convenience. EIO is a one of kind kids cup. Our cap and sleeve fit on virtually any 8oz canning jar. The sleeve is easy to remove and can be left on the cup for washing. How's that for convenience?

We lost the valve... so you won't! EIO's cap is specifically designed without small parts, like the easy-to-lose valve. According to the ADA's recommendations for better dental development, children over the age of one should drink from a cup without a valve (* From The Journal of the American Dental Association, Vol. 135, No 3, 387). Spouts can also be detrimental, as they tend to become chew toys. EIO encourages a healthy, natural transition to cups.

Clearly, it's EIO for years to come. Our modern design appeals to kids of all ages and our versatility allows you to use the jar without the cap as your child learns new skills. The sleeve offers a flashy style and grippy surface no matter how old you are! Never throw them away. That's great news for our environment!

The lid only fits on smooth mason jars and not on the jars with raised glass designs.
John Cole
I love the glass because obviously it's not plastic but also because it really is a good trainer cup to get your little one use to drinking from a real glass.

I think it was hard for him to figure out where the opening was at to get a drink to come out quickly.

DISCLAIMER - I purchased the lid & sleeve without the glass jar, but my review is for the product in general and applies to this model, which includes a glass.

This is a great conversion cup. Before you buy it, though, it is important that you understand exactly what this cup is supposed to do, and what it is NOT supposed to do.

NOT spill-proof
NOT throw proof
NOT unbreakable
NOT for running around the house
NOT for the car

This cup is for older babies and toddlers who are converting to a regular adult cup. It is for use while seated at a table. If your toddler can drink from a cup, but spills around his mouth, this cup is great. If your toddler gets a bit wild with her arms at the table and accidentally knocks her cup over, this cup is great. If you find that ALL other small-sized cups have extremely narrow bases that tip easily, this cup is SUPER great (the jars are nearly the same size at the bottom as at the top). If your bigger kid just has a hard time holding onto a glass, or still wants a "special" cup of his own, this sleeve is great without using the top.

It was not hard for my 3 year old or my 1.5 year old to figure out where the sip-slot was. I just showed them a couple of times. Of course, you have to explain (in super serious "becoming a big girl" voice) that this is a glass... Don't drop it!! Kids are smarter than we give them credit for. But, if we let them run around the house with it just like a plastic spill-proof sippy cup, of course they will spill and break it!

Use your common sense, folks. Don't diss a perfectly good product, just because you didn't take time to train your children to be a big kid.

Also, my 2 had no trouble leaking around the threads - so I can't comment on the leaking issue. Amazon should have no trouble replacing a defective product.

This is a very good idea. I have become less comfortable with our daughter drinking daily from a plastic cup, and this is the best glass sippy cup solution I've yet found. The glass cup is a small canning jar, and the plastic lid will screw on to any standard small canning jar (Mason, Kerr, what-have-you). That's the clever part.

The downsides are minor, in general. The lid can be easily screwed on crooked, in which case the cup leaks. Also, the silicone sleeve traps food and water in the dishwasher, and isn't very easy to put back onto the cup (removal is easy). With cold beverages, you could skip the sleeve entirely, but with warmer beverages or smaller hands, you will want the sleeve.

Finally, since we already had a number of suitable jars, I wish the company would sell packs of lids and sleeves for less money. As it is, I think the lids alone were something like a dollar less than the full cup.

*UPDATE* I just tried these lids on a spare 8oz canning jar I had with a kind of raised diamond pattern on the jar (don't know the brand). The lids leaked - I could not get them to seat evenly or seal properly. So beware these may not work on all jars as advertised.

I have always used little mason jars for my kids so I was thrilled to find the EIO. It's genius that you can screw it onto any mason jar. I just wish I had found it sooner. It's so natural and really teaches them how to sip. I like that it has a learning curve. There is nothing worse than a three year old attached to their sippy cup IMO. Genius! thank you.

I bought this cup and an extra lid/sleeve for my two year old daughter because I am trying to use less of plastic for health and earth reasons. I love that this cup is glass and the lids can be used on any mason jar. I love the glass because obviously it's not plastic but also because it really is a good trainer cup to get your little one use to drinking from a real glass. There is a slot on the lid where liquid pours out so your child can spill it, however that is what I prefered for training purposes and the fact that my daughter doesnt like having to suck on sippy cup spouts. This cup was exactly what I wanted and I will be buying more.

I like this cup- the glass is nice and thick. I was surprised, however, to see that the bottom wasn't covered.

The idea of using a very common and inexpensive form glass such as a mason jars is fantastic.

For sure the child will break them occasionally so being able to pick them up in 6 packs for a few backs at the local discount store is a bargain.

Sadly the design and quality of materials used in the EIO Sleeve appear to have had many corners cut to maximize profits. At $14 a piece we are looking at 1 dollar for the jar, 13 dollars for the lid and sleeve which would cost about 50 cents to manufacture in bulk. If they had spent another 25 to 50 cents the product would have been outstanding.

The lid only fits on smooth mason jars and not on the jars with raised glass designs.

The lid has a raised portion that hits the Childs nose making it uncomfortable or forcing the child to dip his head far back.

The lid is very sturdy and extends down about a half inch which protects against the glass breaking. This extension could be lengthened to cover more of, or even the entire glass plus 1/8 inch so that the glass when sitting down is actually resting on the bottom the lid extension. This would give 100% glass breakage protection.

The threads on the lid are thick and large ensuring no stripping and a strong watertight seal.

The sleeve that protects the side of the glass jar is flimsy, thin, weak and clammy to the touch. When I say thin, I mean it is worthless. It does not extend down under the base so when you set the jar down it rests on glass instead of the sleeve creating a glass breakage concern for when the child sets it down hard. They should be ashamed of themselves for going this cheap. The sleeve should have been modeled after the Life Factory sleeve which is a perfect example of ultimate protection.
