Excellent seller communication. Response clear supoortive.
Thank you!
Not a very organised store, they didn’t gift wrap my item even though I payed for it before checkout
Excellent products as always and really smart delivery. Thanks a million.
Such a sweet toy that will grow with my daughter and be played with for years to come. She is 17 months and loves rolling it along our floorboards as well as discovering different little things we have hidden in the back of the truck. It’s so well made and is lovely to the touch.
We had this ball bought as a present for our dog when she was being looked after by friends. It has become her absolute favourite and very popular by lots of other dogs we encounter.
We also live near the beach so it really helps that it floats too. We use it almost daily and have done for the past 6 months. So needless to say we are very satisfied with the product, tempted to buy a second just Incase (god forbid) we lost this precious favourite. It also fits in the ball thrower sticks which has saved me since being heavily pregnant.
It’s not easy to snag these pieces! Slowly adding to my collection. Love browsing Dragonfly Toys and seeing what they on available on my wishlist. Ostheimer is one of most favourite collection!
The main lesson book is of great quality, and it has a bright colour cover the paper and inside is thick and really nice quality and has good texture and I recommend these main lesson books to everybody
I purchased the Grapat Nins Carla for my grand daughters first birthday, its such a beautifully crafted set and so many ways to play, I know she will enjoy for many years to come.
