I bought this set along with a few Konad Stencils and Stamping varnish. This is now her? 2 years, and neither the doctor nor the double-sided stamps are broke or are beinsträchtigt in their function. Something smeared paint yes, but only because I'm too lazy to säuber (: Anyway, makes regular use, even with Nagellackentfernder and co not to create them, and are like the first day functioning.
A must for anyone with the Konad Stencils STAMPS! (:
