Ikea Trofast / Flisat fitting Activity Lids  
- New and improved version - 
This listing is for the Skeletal System Puzzle Lid 
This consists of an engraved insert with fillable skeleton outline which keeps the bones secure and in the puzzle when being played with. 
It’s engraved with some of the most well known bones 
The bones are made of 5mm White acrylic and the smallest piece measures approx 3cm, so please only use under supervision 
• These are not toys, but are learning aids. 
The insert comes with a small shallow tray to lay the pieces out so they can be placed into their correct spaces. 
There’s a fun small skeleton sensory tray too!
