TopStickMultipurpose Labels - 1000 Blank Sticky Labels, 105 x 57 mm, A4 Sheets, WhiteThe Forest Stewardship Council

I searched for a while to find a label that would fit a DL envelope. I was concerned they would jam in the printer and be difficult to stick to envelopes without creasing. I did not need to worry they are fine in the printer and easy to peel off the sheets and stick down.

Useless labels, I don't know if they're old or just not very sticky but as soon as I stuck it over another paper label, it started to curl around the edges and I had to resort to sellotape to hold it down which kind of defeats the whole idea of a sticky label
