KISREL Silicone Measuring Cups for Resin, Resin Supplies with 600&100ml Cups, Resin Mixing Cups, Silicone Stir Sticks, Epoxy Mixing Cup

Absolutely made of silicone. The size is smaller than the picture appears to be. Perfect to use for epoxy and easy to clean. The durability is 10 out of 10. If I could add something it would be to provide an extra big size measuring cup. Otherwise, wonderful product and I would purchase this again. Easy to pour, value for the money, bendable and very functional.

Excellent, quality is great and very easy to clean and keep them up too!

Easy to read, measuring increments. Easy cleaning up as well

These measuring cups and containers are perfect for epoxy resin. The measurement numbers are a little hard to see, but otherwise, I really like them! The little containers are perfect for mixing colors and can actually be used as a mold if you want to make a shallow half-sphere or sphere. The cured resin was harder to remove than I had thought it would be; however, it was more about getting every piece off than it sticking to the silicone (A little scrubbing and soap did the trick). The included mat is really nice, as it has a shiny finish, while another mat I have leaves a slightly opaque, matte finish on resin pieces. The sticks are pretty good, and resin comes off easily, although I wish they did not have different thicknesses. (I also used some of them for applying facial masks, and they worked well!) Overall, this resin supply set seems to be good quality for a reasonable price, and while nothing is perfect, I am pretty satisfied!

A very nice and complete beginner epoxy pouring kit. They are sturdy and clean very easily if you clean up right after epoxy pours.

It's easy to clean after using the epoxy resin

Included exactly what I was looking for. It’s held up so far to multiple uses already. I especially like the stirring sticks. They are uniquely shaped more like a butter knife and very thin at the end. Which has been very useful. I need to purchase next time the cups with the measurements in black or however it’s done. Because I have to mark these with a marker to see otherwise the measurements disappear when the resin is poured into it. Of course unless you buy the ones that are marked specifically, then they are all like that, not just this one.. This set was great quality and included exactly what I needed. And saved me from buying popsicle sticks, because the stirring sticks works so well. Good value. Will be buying another set again when these wear out. So many uses..

Very flexible silicone measuring cups. And very hard to clean for reuse! Even with coating with release agents, EVERYTHING STICKS, tenaciously. Mold Rubber, Epoxy, polyester, plaster. IT ALL STICKS. I tried using Vaseline, and industrial mold release spray. With very poor result. Best to use a disposable plastic cup. You’ll save on cleaning supplies .
