How sticky are the stickers?!

[Fondue]

Sounds a daft question, but I want a PH sticker for my car (rear quarterlight), but I don't want it to be a permanent feature.
Are any (all) of the stickers easily removable without leaving a sticky mess?

Cheers!

Yep, they're designed to come off easily without leaving anything behind.

Cool, ta!
