StickerMule has been a loyal partner with HackUMass for several years now. Year after year we've chosen to come back to the same high quality die-cut stickers by StickerMule and we are always happy with how they turn out. The design process is quick and easy, and they ship fast if you need your order in for the next week. Our hackers love sticking them on their laptops, suitcases, and collecting them for their hackathon sticker collections. They have yet to wear out and they are quite durable. Overall 5/5 for customer service and a quality product!
