Love the stickers, and love that they come with an insert for my Filofax. HOWEVER.
The stickers can be a pain to take from their backing when they are not on a sheet. I found the POP pack to be uninspiring and odd in it's choices. There were some great packs but I'll be switching to another pack.
I'm in Ireland and the shipping can take an age but it always gets to me with no issues at all.
