I bought these on National Scrapbooking Day and only just began using them in January 2019. I LOVE that they are clear and stack so you can easily store and access the one you want. They are washable - the color does stain, but there is no transfer after you wash them. HOWEVER... I used a brand new one to blend 2 colors together on a 2" circle die cut of 110 smooth card stock and before I could finish, the dauber was coming apart. I then used a different new one to add color to some store bought return address labels, and after about 9 labels of a very light inking, it too was breaking down. Disappointing since I like everything else about them.
