The jumbo blocks allow our eight and ten year old grandsons and their friends to build small forts and other buildings that keep their minds and hands engaged for hours. We gave two sets of blocks as a gift three years ago and they've been outside in the hot Arizona temperatures ever since. The boys asked for another set last year and again this year. The blocks are holding up very well despite continuous rough handling.
Better than edushapes and cheaper. Durable plastic and easy to clean. Can even hold adult weight (140 lbs). Will not wear off like rubber. Amazing. Will buy again when I have 2 kids...or when I become a kid again!
