We LOVE this!

We love our concave finds convex finds convex puzzle. My almost 2 year old spent so long trying to find the matching piece and was so pleased with herself when she was able to figure it out (initially with a bit of help!). As well as being educational, it’s so beautiful and looks great in our play room! Love love love!

Codey Bromilow
Simple puzzle and much more

I just love how the pieces can be used as a simple puzzle for my toddler or added into our building blocks as extra interesting shapes.

Leah Lynham
Well made, interesting shapes and colours

As always Grimms have delivered a quality toy that’s built to last. The pieces can be used for simple colour matching, as a more complicated puzzle or as blocks in play.

Colour and shape sorting fun

My kids are loving this convex puzzle, not only to use as a puzzle but to colour sort, build and even make houses for the lil friends to go in. Just a great add to our collection
