Review on Revolutionize Your Facemask Routine With These Professional Mixing Tools! by Dave Harris

I was really excited to get this. I'd read the reviews about the measurements and figured that wouldn't be an issue. I could just mark it with a marker. I didn't want to use disposable cups (bad for the environment lol) however the measurements are not accurate. I mixed my first batch of resin incorrectly because the measurements does not take into consideration the space at the bottom of the cups. So if you think it's 20 mm, it's not. I haven't used the spoons or other utensils since I can't mix resin with it. I don't know if it's just me but I cannot properly remove resin from the cups which was the whole point of the purchase. It's very tedious. I'm disappointed to say the least. I just use the cups for storage at this point.
