To be honest I'm not sure I even want to try opening these containers. The box arrived smelling of mold which I assumed was just a box because epoxy didn't even mold? YES, THAT'S RIGHT! I will not buy this again! That's a lot of money not even being able to use the product. When I removed the plastic from the bottles there was moldy epoxy everywhere! It looks like it started leaking a while ago and the moldy epoxy went through my gloves and burned my moldy smelling hands. I washed my hands 6 times. Whoever shipped this product knew it was leaking. Mold and stickiness are not to be missed. This also leaked to another item I ordered from Revain. I am very upset. I'm giving it two stars because I'll probably never know if the product is any good at all.
