ZLemma Cardboard Construction Kit - 425 PCS Kids Building Set with Safe Serrated Cutter, Crease Roller, Screws & Nuts, STEM Upcycled Tool for DIY Cardboard Projects, Engineering & Creativity

Good quality, fun tools! I plan to buy multiples of these again for my enrichment classes.

I got these for safety reasons and am surprised at how well they cut. The edges require a little cleanup after, though not nearly as much as I've experience with a craft knife.

The kids aren't as enthused as I am about making fun stuff from cardboard, but it's a great set for when I force them to have fun with Grandma. :)

This is such a fun gift. My daughter has been making a barbie house.

These tools cut well because they are SHARP. I wouldn’t let my younger kids use them but my preteen is cautious so they worked great for her….until one slip of the knife resulted in stitches in the ER and follow-up with a hand surgeon for possible tendon damage. Just saying, BE CAREFUL!

This is a great box-cutting set for kids. It is easy to use, functional, and worth the cost. Surprised by how well it works.

My son loved to use this set to “build” his own hideout! It does require adult supervision and help, of course, but really a lot of fun for child and adult.

I was tired of my son using up all of my glue and tape to make inventions out of cardboard, so I bought him this kit and made a new rule; building must be done with bolts and screws instead of tape and glue. I was impressed with the tools. They are actually sturdy and sharpen enough to cut through cardboard and do the job.
