This set of 2 clear craft epoxy resin bottles can be used to create custom jewelry and diy art projects. To use the art resin epoxy, simply pour an equal ratio of resin and hardener into a mixing cup and stir for at least 3 minute. After the cast epoxy resin is thoroughly mixed, place the cup onto a level surface and pour the contents over your project. Cover and wait 24 hours to cure. Wear glasses and against chemical gloves when handling the casting epoxy resin, and avoid eye and skin contact. If skin contact occurs, wash with soap and water immediately.
