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.

First Grimms purchase and we are so happy ! wood is so special and natural curves are so beautiful to play with they possibilities are endless, we have made so many interesting things so far. Like this giant croissant :). The way they hold onto each other is truly amazing!! Thank you for such a lovely package and note. A lovely experience <3
The quality of this wood is amazing. The coating allows the wood to be stacked with ease. Multiple ways to engage in open ended play
I don’t know where to start with the natural rainbow. But I’ll start off with saying how beautifully made it is, the quality is amazing and other cheap ones you might find, would come no where near how amazing this is.
It’s sturdy, fits perfectly together so the children don’t get frustrated. It stacks so well and is very inviting/ aesthetically pleasing.
There are SO many open-ended, different creative ideas you can come up with. Theirs a link so you can find different things to do/ build with it.
It’s paired perfectly with many things from OWA, but in particular, the coloured semi circles.
My 15month old son LOVES it and my older FDC children, ages 3-4 were busy building for hours!
We still have so many things we can do with it as well!!
We love our natural rainbow! It is so hardy and can endure all sorts of play with my three year old. So glad I decided on this as my first purchase at OWA
Kids and I loved our new addition to our Grimm’s collection. I love the quality the smell and the texture of the wood, also gives us endless possibilities of play in combination with other stacking pieces 💚💜💛
We have purchased this product for our preschool room at an early learning service. The children absolutely love it! It is open ended and allows them to be creative and use their imagination. Not to mention it looks beautiful on the shelf!
This has been a wonderful add to our collection. We love the quality and endless open opportunities to be used so much in creative and imaginative play.
We have had the Wooden Rainbow for a week and it has already been used in so many different ways. For stacking, building, car parks, prisons, beds for nap time (pictured). Both my children absolutely adore it and the possibilities are endless!
Opportunities are endless incorporating the natural rainbow into nature play! It makes all the bits and pieces we find outside to bring into play more magical. We love it
Love playing with these with the grandkids, not sure who enjoys them more!!
I'm not sure who's happier with this item me or my daughter but that's the beauty of these toys, they appeal to all ages. Beautifully made with endless options for play. So happy with our rainbow and the service from Oskars Wooden Ark. We will be back to add to our rainbow collection!
We love the rainbows. Perfect for creative play and building imagination!
I love how the natural wood grain of this rainbow and other grimms natural toys makes each piece individual and unique. As wooden toy lovers our family enjoys the look, feel and versatility of this natural rainbow in play very much.
I can’t believe the open-ended opportunities for play this piece has. I run a family daycare and have found it’s great for all ages. What an amazing product!
My favourite tunnel by far. It's slightly sturdier/stronger wood than the coloured rainbow tunnel. I love that you can really see the gorgeous woodgrain. Very happy with my purchase.
Haven’t had this for long but our 2 year old has already made caves, bridges, boats, amazing towers... everything but rainbows! So glad we opted for natural.
We also had lovely service from Oskars Wooden Ark, will defiantly be buying from them again!
I’m really happy with the natural tunnels, my toddler and husband have started playing with it and the options are endless. I thought about buying the rainbow but I’m glad I didn’t as I feel this is so versatile and you can add colour to it with other items.
Gorgeous tunnel!!
Great quality item. The play options with these are endless. Myself and my husband enjoying building with them as much as our toddler.
The often overlooked natural tunnel, is an amazing addition to a playroom, with it's endless possibilities. Being natural adds an extra element to play, it reminds children where wood comes from, and you can see the grains in the wood making it all the more unique and special.
