Great for lots of things!

Small amounts of hair dye for root touchups, acrylic paint for craft projects, glitter to keep sparkly projects tidy, glue that must be painted on. Use as condiment cups for outdoor dining or parties where disposable beats washable, or even dessert cups. I've used them to freeze dog popsicles in the summer, and as molds for soap. I'm sure I will think of many more things as time goes on.

They're thin and a little bit soft, so you can't expect to hold a full boat of lead weights or anything extra hevy, but they're plenty stiff enough for everything else I have tried.

I use these in hand-dyeing to measure out the correct weight of dyes to get repeatable colors. This medium set is useful for measuring dye powders to approximately 1 liter of liquid concentrate. I use an inexpensive digital scale that measures down to 0.1 gram. When mixing colors, I use these for all the colors, just tare the previous dye weight, and go on. I also use it to weigh out the alginate and mix that with the dye power thoroughly before adding to the liquid mix.
These are inexpensive enough to be disposable, though I suspect that some may wash and rinse and reuse them. These are thin plastic, and not really suitable for re-use, but they might last through several re-washes; I have not done that. The plastic seems to be thin milk-jug type and does not hold onto the dye powder much, but there is always some left in the weighing boat.
I use a flask and magnetic stirrer to mix my dyes, so I start the liquid stirring, getting a weak vortex, and then add all the powders to the liquid at once. The magnetic stirrer does all the mixing and usually in a minute or so the volume is mixed well.
When using alginate, it is necessary to allow time for the alginate to "bloom"; I usually allow several minutes to be sure that the alginate is well disbursed, then remove the stirbar and impatiently wait for the alginate to bloom and thicken (some times having to wait for 12-48 hours to get good thickness).

They definitely serve their function, but are super light weight. I use them to mix pigments for cosmetics and they are a great size for it.

These are awesome. Minimal stick and much less messy than using a paper for weighing. I got the small version too and they also work great.

Needed these for a science project. I wish they came in different quantities. I really only needed about 10 max but reasonable price and quality. The shape for each was not uniform which would be the biggest negative.

if you are careful and wash them thoroughly you can re-use these disposable dishes for a little while. They are exactly what I wanted.
