Earlier this year I purchased some postage from Zazzle with my designs. I expected them to be matte or semi-matte like most postage stamps, and was surprised to find they had a high quality glossy finish, like Zazzle's stickers do.
So, when I bought some of Zazzle's new address labels with my designs, I fully expected them to be glossy like Zazzle's stickers and stamps. But they were matte. Go figure! Can't say I'm not a little disappointed. I was wondering why the cost per sheet was less than the stickers, and that explains it.
