Happy HCO300 Original Cardboard Box 3D Puzzle, Pack of 6, 13x2,6x23 cm

My students love these. They provide endless entertainment and great problem solving skills :)

I am yet another one who yearned to find this blast from the past. Stumbled across it here on Amazon, instantly into my cart it went. Was everything I remembered. Assembled each into a cube then back flat for storage. Lots of good memories, and lots of fun. Thinking my grandson will get to enjoy these with me in a couple years. I suggest waiting until at least six. Eight may be better depending on the child's interest. And by no means is this just for kids. It can help anyone develop 3 dimensional thinking so long as they have interest and a little focus. It is truly an educational toy but we don't have to say that part out loud. I'd have loved this at six, and at over ten times that I still love these.

I wish I made this myself. Person who made this is brilliant. I usually give one of these does someone I felt that needs one. Great puzzle for any age as a gift.

After searching for YEARS I was finally able to locate these foam cube puzzles that I had when I was 7, over 30 years ago...I once found (not the same brand) these cubes in a store in Tennessee and quickly fell in love with the idea of a 3D puzzle that I could take apart & reassemble over and over. When I received these in the mail I immediately opened them, and (nicely) tore them apart!!! I must have muscle memory, because I put them all together in less than 10 minutes. This is so satisfying, to be able to pass these on to my son. I tried to order the other versions but the website that sells them does not ship to the US. Hoping that changes one day!

I teach at juvenile hall. The boys need something to fidget with. The three dimensional cube puzzles are perfect. No hard or sharp parts that they can use to hurt themselves or the furniture. The puzzles are challenging. It keeps them occupied and out of trouble.

I remember this from years ago in Europe. So glad to find it. It’s portable, quiet and forces you to slow down and work through it. The frustration: reward ratio is perfect. I’m quite bad at logical quizzes but I’m able to do this.

Had these as a kid. So fun to see them again and play with.

8yr old boy LOVES these. They use them at school and wanted some for the house.
