Copperkids...
When searching in ebay, remember many people dont "get" stamps...so they might not even mention a brand...search on the design ie Holly wreaths or whatever it is.
Also there are often mis-spellings/typos so check what seems like common ones.
aka throw your net wide if you are not coming up with enough.
Do you know how to sort? Tell it to sort lowest price (plus shipping) first. That isnt perfect-they go up/down a bit, I dont know why but it's a start.
I always advise sellers to clearly show sizes on a ruler/grid but at least tell us in the description.....and to show us the rubber side. "Loved" stamps mean a lot of things.
If you ever have any Qs...PM me and I will try to help you out!
