CrunchLabs Build Boxes are designed for kids ages 8-12+. 

We test every product with 3rd-party testing agencies to ensure the products comply with US and EU safety standards for kids ages 8-years and older. 

Parents and guardians can gauge the appropriateness for their kids, but we have worked hard to ensure that they’re a blast for the intended age range - and for anyone who loves learning!

Each Build Box contains a chance to win a Platinum Ticket* like the Golden Ticket in Charlie and the Chocolate Factory.

How it Works
One Build Box is selected at random and a little extra piece of hardware goes inside. The lucky winners visit the real life CrunchLabs to meet & create with Mark Rober.

*No Purchase Necessary. Ends 5/31/27. 50 U.S. & D.C., 18+. See Official Rules.

Nope! All the stuff you need to make the toy is included in the Build Box, even batteries.

You will need an Internet connection and a kid-safe device to watch the Mark Rober video episode, but you don’t need the video episode to complete the build.

If there are parts missing, go to your My Account portal and visit the page for your toy to order FREE replacement parts. If you have further questions contact help@crunchlabs.com.  

Yes! We design each toy to be a little bit challenging for kids 8–12+, in the same way a good puzzle is challenging.

Each box has materials to guide you:

• A step-by-step illustrated instruction booklet
• An instruction video where Mark Rober walks builders through each step

With the help of the instruction video and booklet (and just a dash of tenacity!) tons of kids are able to build and play independently with Build Box.

We design each Build Box toy to take an average 30-60 minutes for an 8-12 year old. 

Every kid is different and build times will vary!

Currently, we don’t offer an option to purchase individual Build Boxes (though that may come down the road). We have carefully crafted multiple years of engineering fun and learning into our box sequences, so we think a subscription is the best.

Of course! We test every Build Box product with 3rd-party testing agencies to ensure our products comply with US and EU safety standards for kids ages 8-years and older. 

The safety standards check that the toy is safe and sturdy for its intended play, and that unsafe chemicals don’t make their way into the toy during production.

How do we calculate international shipping?

Here’s the bottom line: We’re doing our very best to deliver high quality products to you with the lowest shipping rates possible. Duties and taxes, along with other rates, will vary based on your location and subscription type, so please see the total calculated during checkout.

If you'd like a more detailed explanation of international shipping costs, please read on:

For non-US addresses, your total shipping fee will be shown to you during the checkout process.

Shipping internationally costs us a lot more, so we charge a little extra. We apply the value of domestic shipping ($3.95) within the US to your international shipping cost. Various extra taxes (including VAT) and duties may be collected upon checkout.

Some countries are subject to Delivery Duty Paid fees of about 70% per box. All associated charges are calculated at checkout.

Some countries are subject to Delivery Due Unpaid fees but are exempted from VAT, so these charges will NOT appear during checkout for regular subscriptions. However, bulk orders may be subject to VAT.
