Coating cup with a double bottom structure and coating stick with a square cross section. The coating cup has a double bottom structure that is difficult to tip over and easy to hold, making it the perfect capacity for "EZ EPO''. The inside of the cup is shaped like a mortar, so you can use up the epoxy without having to scoop it up. The coating stick has a square cross section that is difficult to roll and easy to hold. The indentation on the tip of the stick fits perfectly when leaning it against the coating cup.
