I have to admit that I was not convinced when I bought these. My daughter (five) wanted her room to be pink & lilac with "butterflies, fairies, hearts and flowers" - very firm opinions on interior design for a five year old but keen to oblige I found these on amazon. I didn't have any great expectations but was very impressed. The design and production is very professional. They peel off their backing sheet with no problems - not a hint of tearing and very easy. They stick a little like a very high class post-it-note - not really like a classic sticker - which means that they peel back off easily when your five year old tells you that they're in the wrong place.
& in case you were wondering - there are definitely enough in the pack to recreate the graphic on the photo - a good mix of big ones & small ones.
