I’m hearing different things about whether or not these pencils are waterproof or not. I’m also not seeing anything on the Nyx website about them being waterproof or not. All I can say is my pencils came off very easily with makeup wipes and Ponds Cold Cream Cleanser. In addition, I swatched the colors on the back of my hand. I washed my hands throughout the evening, and the colors stayed on pretty well for the most part. I would suggest having a backup waterproof eye makeup cleanser on hand if you tend to wash off your eye makeup with water.
