Product arrived as described. Easy to assemble, a little time consuming but sturdy. Can be used in so many ways as a child develops. Would buy again

These were great till they came under attack by our toddler. Some crushed easily under the rocking chair, some seemed to want to come unfolded. They don’t stack well when they become caterwonkey.

My 4 year old and 1.5 year old love these! They take turns building towers to knock down and trying to build castles. The blocks were easy enough to assemble, but I do find that on the smaller blocks the flaps try to come undone. I think a bit of clear packing tape on the seam should keep them together nicely though. Also these blocks are indeed sturdy! My husband and I both took turns standing on them because we didn't believe cardboard would hold our weight.

These are not fun to assemble. By the 20th you get the hang of it. By that point you are about done assembling. However, my kids 2 and 3 years old frigging love these blocks. They play with them every day. More so than anything else. They are a good buy but annoying to store, clean assemble etc. like most kids toys. I bought a plastic rolling bin that slides u see a bed. They almost all fit in them. Then we slide under a large chair.

Several years ago I purchased a similar set for my, then youngest, grandson. He and his now 4 year old brother have had many hours of play with them but they were starting to show some serious signs of wear but the boys just didn't want to give them up so my son suggested another set for Christmas :) The boys are thrilled that this set came with different sizes and colors and my son is confident that these will hold up as well and as long as the previous set.

Our 4 year old loves this and builds stages, letters, towers while our 2 year old kicks them all down with a big grin.
