A review for Front adhesive stickers by Paul Rickert.
These stickers are nice, but they don't work so well as promotional items. the backing is opaque so you can't see the image. I've gotten mostly confused looks when handing them out. You have to have an example put on a clear surface to show people, which kind defeats the purpose of the concept of having a small easy to carry and distribute pocket promo.
The quality of the sticker itself is very good, it's just not very usable for what I need.
