Fantastic Colours, Size and Quality

Love the bright colours, the beautiful texture and finish of these large balls. Perfect for my 1yo, who doesn’t try to put them in his mouth. They also fit perfectly in our Hip Kids ball tracker, as an unexpected bonus. Wish they came in a sturdier package than a cardboard egg container as my son has already ripped it in half (to be expected) - I feel like it was part of the fun of the toy for him to put them back inside though so didn’t want to withhold it.

Fantastic wooden Rainbow Balls

My 10 month old loves these bright and colourful balls!
Unfortunately so do my dogs who got to them the other day! Great addition to any play, just keep them out of the clutches of any ball-obsessed dogs!

Grimm’s rainbow balls

Perfect size for my little one to play with. Nice bright colours and amazing quality, as always.

Daile Kelleher
Great addition to our play

The balls are a good size and vibrant, they will be a great addition

A favourite

These are a favourite for both my sons. I was really impressed with the size and quality when we received them. Considering getting a second set in another colour way.


This is the ultimate open ended toy. The bright colors and grippy texture make it an absolute must have!

Loved by parents too!

These rainbow balls would have to be my 1 year old daughter's favorite toy! She plays with them daily, her latest thing is to roll them down her slide.
We thought we had 'lost' the orange ball for 3 days, we turned the house upside down and eventually found it in a drawer! The relief we felt when we found it 😄

I can’t get them out of her hands.

All I can say is I never expected a 10 month old to love something so simple so much.

Expansion item

Really useful for marble runs, suitable for 1 onwards I think as they’re not small enough to be eaten!

Gorgeous purchase

My nearly 1 year old, loves his rainbow large balls. He literally spends hours rolling them around on our floorboards chasing them as they roll. Their also great for ball runs and apparently they’re also his favourite musical instrument-the click they make when hit together is what he loves! So happy with this product!
