National Geographic Jumbo Cardboard Building Blocks – 45-Pc. Extra-Thick Cardboard Bricks for Kids, Build a Castle Play House, Indoor Playhouse, Large Building Blocks, Kids Giant Blocks

I am very impressed with these cardboard blocks. We have used a different brand of cardboard blocks before, but these are thicker cardboard, sturdier construction and slightly larger. I love the castle theme and variety of pieces that are included. One set is enough to build a sizeable castle wall. Assembly was simple with the included instructions. We had a convenient place to store ours, but once folded, they will not easily be unfolded to store flat, so keep that in mind when purchasing.

We got these as a birthday present for my daughter who loves building with blocks and wanted something bigger. SHE ABSOLUTELY LOVES THEM!!!! She plays with them all the time and has a blast! The color/stones are perfect, so so much better than the basic blue, red, yellow bricks I used to play with as a kid. My daughter is 3 and has stepped on a few of them before and had no issue with them breaking or deforming so I would say they are pretty durable. They stack well and you can make a different set up every time you play. I love that some of them have windows with torches on them and that there are four different sizes included (big rectangle, smaller rectangle, square, and triangle!!!). The set also came with two paper crowns, a jaw bridge (cardstock and high quality), and a little card with information about medieval castles in Europe!They do come flat and need to be assembled which was a little time consuming, but the instructions were easy to follow and once you get the hang of it you can breeze right through the building process.I HIGHLY recommend these over the normal, boring blue, red, yellow cardboard blocks- you won’t be disappointed. The way my daughter’s imagination runs wild while building with these brings me so much joy. To me these were definitely worth the money that we paid and I would do it again and again!!!

My 3 year old grandson loves to build with these. They are sturdy enough to stand on yet light enough to cause no damage when they hit people or things! Came with very good directions for assembling each cardboard brick but it is a bit time consuming. Well worth the effort though!

These were perfect building blocks for my 1.5 year old nephew. He loves to build & knock down so wanted something that would not hurt him when they fell. They come flat so took a few minutes to put together. After a couple, you get the hang of it so goes a lot quicker. They are sturdy enough for him to stand on without denting. Hours of fun that will last for years to come.

This is a pretty cool set that toddlers will love if they like building things. Just keep in mind that all of these blocks are made of cardboard but the cardboard is thick and folding them according to the instructions is kind of tedious but keeps the integrity of the structure. These should be kept indoors only and because it is cardboard I don't think they'll hold up over time but we'll have to see.

My preschool kiddos loved this blocks during our fairy tale theme. They are easy to use and held up to 18 2-4 year olds. They really enjoyed the size of these blocks and spent quite a bit of time building castles.

Kids love it, super fun! A pian to put together, but you only have to do it once. The blocks are made out of a very durable and tough material (about 1/8th" thick cardboard). As long as you don't get them wet, they should last for a long time. You need to buy 2 of the large boxes in order to have enough blocks for a proper play castle one is simply not enough, unless your Simon Birch. These are obviously just little cardboard boxes with a graphics printed on them, but you're not paying for cardboard, your paying to expand and encourage your child's imagination.

great product! Very strong and sturdy
