Cups get stuck together but good product great for the price

I cast resins for making pens. I normally use HDPE cups, but they are expensive even though they can be cleaned of hardened resin and re-used. I was looking for something cheaper than HDPE, and these are certainly cheaper. They are TCP. The downside is that they do not release hardened resin (I use Alumilite polyurethane) so they become one-time use cups. Which makes them cost about the same as the HDPE, though I do save time by not having to de-resin the cups. Not sure if I will continue to use these or go back to HDPE. Cost comes out about the same, but I do save time and that is good. However, they are good cups if you are OK with single use. Be aware they are thinner than HDPE so use caution when picking up a full cup. It isn't as rigid and you could spill. Don't ask me how I know this........

Quality product

The measuring marks are great, many options to choose from. The cups are a bit flimsy, which is a plus and a minus. On the "bad" side, they can flip over easily as you are pouring liquid into them. On the "good" side, because they are a bit flimsy, it is very easy to make a "spout" to pour from. I used one measuring cup 6 times in one deep epoxy fill project and it worked great.

Holds up well when mixing epoxy resin but not sure about the accuracy of the volume graduation. I always weigh and not rely on the markings, but it’s doing the job I need it to do.
