Is it FriYAY yet?! It probably isn't but at least we are one day closer and looking fab with our funny coffee mugs. Mugs are 16oz double wall, BPA free. This design is a vinyl decal, don't worry it won't just come off with regular use. The vinyl I use is outdoor sign quality and is considered a permanent application. Not sure about vinyl products? Shoot me a message I'd love to yell you why it's the best.
