For all my professionally printed projects, I’ve been using Express Stickers since 2010. Great people to work with! Always helpful, easy to contact by email / live chat or online, the process is really (really!) fast, and the quality is great. The colors are spectacular … and just what I envisioned. Oh, did I mention great prices? I never hesitate to recommend Sticker Mate. It’s a wonderful resource for artists. All best wishes to you!
