Gelarti stickers

[tummytickler]

Anybody used this? DD really wants one for Christmas, but they look awfully expensive, for a few stickers and a plastic 'desk' to colour them on.
Am I missing something - are they amazing?
If your dc have had one, could you do a mini review for me please, before I waste £20 on potential tat. She want the Charmies too, but I have already decided that looks like it would be very disappointing, so not getting it!
