Our SmartKidsPlanet initiative began in 2017 when 3 geeky and dedicated parents saw a gap in the children’s toys and games market. An opportunity was spotted while we struggled to find toys and games for our kids which enriched their minds and guided them toward science, art, math and construction. The trio then knew that their paths were set, establishing an online shop with a comprehensive range of intelligent toys for babies, children and young teenagers.

With offices based in California, our SmartKidsPlanet team enjoys a daily growth in our presence within the children’s educational toys market. We love our new place in life, and we love helping young minds with their growth and skill development, all while having as much fun as possible.

Great tool set! My son loves it!

Awesome product! We have built multiple planes, helicopters, cars and trucks. My son absolutely loves this product and gives us great one-on-one time! The pieces are solid and sturdy. I just wish they included extra wheels, nuts bolts etc.... easy to lose pieces! Also, the carrying case is a solid construction! My son loves to use it for the wood pieces and other toys!
Highly recommend!

My son loves open ended toys.. The moment I saw this, I knew I had to get it for him. It's really well made, smooth edges (safe for kids to play). Also love, that it's all wooden. The box is also really well made and great to keep the tools. There are lots of different structures & things that can be made using the parts provided.

Adorable Toddler tools

2.5 years old is a tough age range for which to buy gifts. My dear friend has a little boy who wants to help his big brother (9) build stuff, but not get into trouble. This set is perfect! Each little smiling tool will warm his heart and buikd confidence. They come with a big boy toolbox that clasps together. They are all bright and vibrant wooden tools, that feel sturdy.

I had to take it away from him

Ugh! I had to finally take it away from him (my husband) so I could wrap it for our granddaughter!

I bought a different set initially,...sent it back because it was too cheap. This one is nearly double the price, but well worth the extra money. The screws are better threaded than most of the real screws you get with anything you have to assemble these days. The set comes with some pictures of things you can make. I think Some netting to hold the smaller pieces in the box would be great. Maybe grandpa can devise something.

Handy Manny in the House

My 3 year old loves this set. he keeps calling himself Handy Manny, although some of the colors of the tools are different. The box is really nice and makes a great carrying case that is easy to use and the tools are sturdy and super cute. The set has a small number of building pieces which makes it a great beginner set as there are not so many pieces it is overwhelming for a younger child. I would definitely recommend this set for a 3 year old.
