Epoxy Mixing Ratio Cups (2.5 Quart - Pack of 12) - Mix DIY Countertop Epoxy Resin Kits in Disposable Calibrated Mixing Cups! Ratios are 1:1, 2:1, and 3:1! (Stone Coat Countertops)

These are working out great for me. I use them for two part deep pour epoxy resin, not stone-coat.The size is perfect, big enough to hold both parts and still have room to "stir" without things overflowing.They are sturdy enough that I can mix/stir right in these cups without the sides pushing in (like if you use a plastic cup). You can stir a lot of resin, with strength, and they do not crumple.I also like that the various ratio's are on the cups. I alternate between 1:1 and 1:2 epoxys depending what's on sale and yet I can still use these cups easily.I have wiped them out and reused them but I've also forgotten and had to toss a couple. Either way I'm good with the cost/quantity (I don't feel guilty if I have to toss, etc.).

These cups are great for mixing epoxy, my only complaint is they don't have ounces written on them. When I mix epoxy, I figure out how much I need in ounces, so I just used water to figure out what marks to fill to. Not a big deal, but would be helpful. Otherwise, these are nice sturdy cups for mixing.
