STEM Kits Advent Calendar 2023 for Kids Age 8-12, 10Pcs STEM Project Toys with 12Pcs Brain Teaser Puzzle Toys for Christmas Countdown Calendar, 3D Puzzles Wood Stem Science Toys for Boys Girls Teens

This STEM toy kit comes with multiple pieces/toys, which need some assembly to get little brains thinking.Once assembled they can be played with or taken apart to be built again, which my little nephew has enjoyed doing and has kept him entertained (for a while at least).They're advertised as advent calendar toys, which is obviously healthier than chocolate and will be a bit of fun each morning.All in all, it's a good STEM toy kit.

This is a fantastic product but I wouldn't call it an advent calendar. It has a little bag that is for the first to tenth days of December, where you put a different activity set each day. The sets are really fun to make but a younger child will require adult supervision. One of the sets has a printing error (pre-cut holes in the wrong position) so the bits didn't fit together as suggested but the item still worked and we problem solved a solution, extending the learning experience. For days eleven to twenty-four, it is more like a traditional advent calendar with windows to open with puzzles behind each window. For the price of this product I think it is really good value as each day your child will have something different to make or solve. I am extremely impressed and will recommend this 100% even with the printing error.

Good material less price .I order this for my son. Each block wrapped separately with instructions & diagrams showing you that how to build each design. You can make things easily. I more this product more than my son. You can use this product in school project also.
