Review on 📏 20-Pack of 8oz Graduated Clear Plastic Measuring Cups with Wooden Stirring Sticks - Ideal for Mixing Paint, Pigments, Epoxy Resins, and more by Mindi Gefroh

I prepared some pigment and mold, I have the cups I just received (this is an order for 20 cups) (I use three, one for resin, one for hardener and one, in which I mix everything together). ) on my desk. Mind you, I have photos. I have a table lamp with a 25W bulb. About almost 4 feet above the table. After preparing my area, I noticed that all of my cups have huge ridges and look like the parts were melted/vacuumed. I assume this was due to the heat of my light? From a pretty great height. I tried to pull them out but I couldn't. Considering I use them for resin and it's a heat/warmth reaction I wouldn't trust them at all. Sometimes cheap is good, but in this case it seems dangerous.
