BNTO (ben-toh) is our newest canning jar adapter for bringing great food with you on the go! We took inspiration from Japanese bento boxes and created a conveniently shaped insert that separates a canning jar into two compartments so you can mix or dip like a champ.

Edit to add: if you like Noosa yogurt, and they sell the single-serving cups of Noosa in four-packs in your area (I get mine at Target), those cups also work well for inserting into Mason jars, same as the Cuppow Bento cups.
So, after reading another review that complained of leaking, I conducted a little test comprised of 2 parts: 1) water in BNTO cup + empty jar bottom, and 2) empty BNTO cup + water in jar bottom. In both cases I used the same metal canning jar lid, screwed it on tightly, and shook vigorously over a dry paper towel to detect leaking.
Results: Water in BNTO cup did not leak, but water in jar DID leak a little with very vigorous shaking. In both cases, found it helped to completely dry the lid parts as well as rims of jar and cup before closing - otherwise some of that water sprinkled out, looking like leaks.
Conclusion: this product is designed for liquids in the cup but not in the jar??? Looking at the photos and video from the company, it kind of makes sense, because they all show solids in the jar - salad, granola, celery, chips, crackers, fruit. If this is intentional, they should provide use instructions. But I find no mention anywhere of this limitation on the website or packaging.
Thinking about the design...to create a seal with the jar, seems like rubber/silcone against the glass jar rim would be necessary. I also wonder about the cup's durability. I can imagine the rim getting nicked, or the round shape otherwise distorting, preventing a good seal. Time will tell!
Giving this 4 stars instead of 5 now, but I do still like it so far and will just not put liquids in the bottom part.
- Fits plastic lids (will not screw all the way down, but will screw on and keep everything secure)
- Easily to clean
- Made in the USA
- Sturdy plastic
- Holds a lot (peanut butter, dressing, granola, extra fruit or veggies)
- Works with multiple sized mason jars
This is worth the price and I would highly recommend this product! It works with multiple sized wide-mouth mason jars and I love that it is so adaptable.
