Timeless Wooden Toys For Open Ended Play & Learning
Grimm’s Wooden Toys are crafted in Germany by a family-owned company dedicated to open-ended play, natural materials and timeless design. Since 1978, they have created sustainably made wooden toys that support creativity, learning and meaningful everyday moments for children and adults alike.
Each piece is designed with simple forms, soft colours and tactile wooden textures that invite children to build, stack and imagine freely. Guided by Waldorf and Montessori principles, Grimm’s toys encourage exploration, problem-solving and imaginative thinking without limits or instructions.
Made from sustainably sourced alder, beech, lime and maple wood, every toy is carefully finished using safe, non-toxic colour stains. Built to last for generations, Grimm’s supports fine motor development, sensory learning and creative confidence through beautifully crafted wooden play.

Essential to pair with the Grimms rainbow. We have used these to build fairy/gnome houses to building towers to the ceiling! So much fun
Goes well with the rainbow. Good for building and runs. Also looks great as a base.
My kids were so happy to start playing with the semis. They work harmoniously with the rainbow, extending its building capabilities tenfold and opening up the possibilities of open ended play even further. Before my girls were using the rainbow on its own as houses, now with the semis the houses can have roofs and stories. They build huge apartment blocks and huge houses with roofs and last week Indi added a rooftop playground using the nins Carla. The perfect next purchase after the large rainbow for people just beginning their wooden toy journey
Lovely
These are great, and so we’ll made. They pair well with the rainbow for building / ball run projects.
For anyone with the Grimms large rainbow, these are a must buy. They unlock a vast wealth of playing potential!
These semi’s have been a wonderful addition to our natural tunnel to make ball runs, apartment buildings and zoos. The kids have also used some individual colors to make sunsets, lakes, oceans. A much loved addition to our collection.
We love all the different things the kids can now imagine and create using the semi circles, rainbows, rainbow friends and rings. Such versatile and beautifully made products.
A definite essential item for every playroom.
My 2 year old has owned the rainbow for some time but it wasn't until we got these that my son started building more than tunnels etc. Also work well as building boards with blocks.
Just like Mac goes with Cheese, semis go with rainbows!
Used for making cakes, apartment buildings, staircases to castles, plates for picnics, face bases, the list goes on, our semis have become an integral piece in our collection. So glad we opted to buy these alongside our rainbow!
Regularly used at our house with the rainbow to create houses for the Nins. Also used for ball runs. Great addition if you have a large rainbow.
I purchased the semi circles and rainbow balls to add to our grimms large rainbow and they expand the play potential! My 1 year old loves to deconstruct and interact with the ball runs. Beautiful to boot. Fast delivery in recyclable packaging.
My children aged 3, 1 and 1 absolutely love these!
Paired with the rainbow create so many building opportunities, we have created towers, made ball runs and even used them for colour matching activities!
Can’t wait to see what else we use them for in the future x
If you have a large rainbow, the semi circles are a must. The towers are incredible!
The semi circles also get a lot of use in small world play (eg. As water, grass, sand) and colour sorting.
Great for run balls and to make towers with the rainbow. My son loves the “stairs” as he call them. Beautiful colors and quality
We got our semi circles last week and they’ve had our daughter immersed in her play every single day! From building with her rainbow, beds for her bubbas, plates in her kitchen, these are so versalite and SUCH good quailty! 🌟🌟🌟🌟🌟
Anyone who gets a grimms rainbow soon finds out that these semis circles are the perfect addition. The same quality craftsmanship and vibrant colours. So please we added these to our collection
Since receiving our semi circles a few days ago they’ve been used to build towers, marble runs, bases for animals (grass, water) and for colour sorting. Definitely worth the purchase, especially to use alongside the large rainbow.
Such a perfect addition to the large rainbow. My children have enjoyed making towers with them and working together to do so
The perfect addition to our large rainbow. I was very impressed with the quality and thickness of the semi circles.
We love our semi circles! The semicircles are an amazing extension to the Grimms 12 piece rainbow and building sets. It extends children's play possibilities and promotes further thinking and planning by enabling children to build more extravagant, complex towers and houses in combination with the rainbow or other Grimms building block sets. They can also be used as a base for colour sorting and counting activities, the possibilities are endless.
