Bought these to accompany my cards this year. The postal service can throw around mail like rugby balls, which mean these are a shrewd buy. The mail is kept together well, and adds branding too!

Misleading Envelope seals

Verified Buyer

I bought these as an alternative to the lables stickers, as I thought they looked liked different sizes on the website, and these would be ideal for my smaller products bags, instead of the larger regular sized stickers instead, but when I received them, they were exactly the same as the normal stickers, and I could see no difference at all, and i stupidly paid more money on these, thinking they were a different size, and I bought 240 of them.
