Screen-free activities that kids actually want to do are harder to find than they should be. Most options either lose their appeal after a week or require so much parental effort that they no longer feel worth it. KiwiCo was built to fix both of those problems.

Since 2011, the company has shipped over 50 million hands-on project kits to families in 40+ countries, each developed with child development experts, extensively tested, and calibrated to exactly what kids at a given age can do and are curious about. The result is a subscription that stays exciting month after month. And right now, first-time and returning subscribers can use KiwiCo coupon code REVIEWED to get 50% off their first crate.

What is KiwiCo?

KiwiCo is the original monthly STEM subscription box for kids. Each crate is developed in partnership with child development experts and educators, and every product goes through more than 1,000 hours of development and testing before it ships. The company's approach is backed by research, including a recent collaboration with Johns Hopkins University, which shows that hands-on, project-based play is a powerful way for kids to absorb and retain new concepts.

The result? Unique monthly crates that feel like a fun surprise in the mail and quietly teach kids to think like engineers, artists, and scientists along the way. Not bad for something that keeps them off a screen when they first build their projects and for many more moments with extended play.

We've tested KiwiCo firsthand; you can read our full take in our hands-on KiwiCo review.

Which KiwiCo crate is right for your kid?

The KiwiCo lineup is organized by age and developmental stage, so rather than a one-size-fits-all box, you can get something customized to exactly what your kid can do and is curious about right now.

The four featured crates below span ages 3 through 12+, and the KiwiCo promo code REVIEWED takes 50% off of these monthly crates. (Single crates are also available if you're not ready to commit to a subscription.)

The original KiwiCo line and still the most popular for good reason. Kiwi Crate projects sit at the sweet spot of imaginative and educational, as kids build, create, and experiment their way through concepts in science and art without it ever feeling like homework.

For the kid who has outgrown crafts and wants a real challenge. Tinker Crate projects are STEM-forward and genuinely complex, with activities that focus on circuits, mechanics, and engineering builds that take real focus to complete. It's the crate for the kid who takes things apart to see how they work, and a great option for parents looking for something more substantive than a screen.

KiwiCo's newest offering is a little different from the monthly crate format. The Spinning Sand Garden is a standalone kinetic art piece that kids build and customize themselves, combining a satisfying hands-on build with a meditative feel. A great gift for an existing KiwiCo subscriber, or a great option for a birthday present that will deliver extended play.
