  • I'm soooo excited - this is AMAZING. My grandson & I LOVE these types of activities and l've looked at other kits before but just attempt my own. By doing that - I realize the time & effort that goes into it. This is fantastic!!!

  • My child was so happy when I opened it. I homeschool him and the ABCs and 123s are easy but it's daunting for me to put together my own art and crafts projects for him with all the other things I juggle on the daily. I'm so glad I found them!

  • I have no idea how y'all can only charge $40 for these, they have so much stuff in them! Y'all really hit it out of the park with this box and I can't wait to see next months!

  • We loved our first activity! 😄 The boys were very engaged with it for a long time, probably about 20 minutes! It’s so nice to have everything you need right there in the box!
