Uplifted my daughter

My daughter has been ill the past few weeks, so I thought this would be an awesome kit to uplift her. She loves building, and this kit let her dive into her science and art side. It was very easy for her to understand and create. It was all for a low price, so it didn't make a big dent to my bank account.

High quality materials

A very great quality kit - all of the wood, tubes, paints, bolts, etc. Not only that, but it also came in very fast.

Your kids will build this easily!

If you are worried about your kids having trouble understanding how to create the excavator, don’t! My daughter had no trouble building it within a short amount of time. She had so much fun and loved how it even came with different colors of paint for it. Now, I am on the search for more kits like this. Thank you Open the Joy!

My little nephew's birthday gift

This was the perfect birthday gift for my little nephew who is interested in creating. Not only did it require a lot of brain power, but it also allowed him to dive into his creative side. He loved everything about it.

Brings building for children to another level

My son is in love with legos, so I thought I could bring it to another level with this kit. I personally have never seen anything like this before, but it is amazing!
