Review on Custom Shop/TCP Global (Box Of 50 Lids - Quart Size) Exclusively Fits TCP Global 32 Ounce Paint Mix Cups by Doug Virden

I used these measuring cups to measure epoxy and hardener in a 1:1 ratio. After the second pour I noticed I had more hardener left than resin. It turns out that the 1:1 ratio is actually a 1.15 to 1 ratio. I measured with a lab grade graduated cylinder and 115ml makes it to line 1 and another 100ml fills the beaker to line 2. No wonder my epoxy countertops don't cure. ! I spent about $100 on epoxy and countless hours of labor. Also, only 10 out of 12 cups were intact when I received them.
