Review: Not just for tub time!!!! - When visiting my grandson who is 5 now, we always go to the "school store" where he picks out a new toy. He wanted a box of Blockaroo's, but when I saw the box I tried to get him to choose something else. He was not having it. I kept telling him this is for babies, not big boys who are in kindergarten. Again... he was not having it. I gave him much more expensive options.... he still was not having it. I gave in, and got him the small box at the store. O M G..... these blocks are amazing, and such creativity. I immediately got on desertcart to order the big set of 100. Yes they are pricey for some, but worth every penny. I also ordered two of the smaller sets for my other younger grandson back home, and guess what... the 6 year old took over and started making all kinds of things. These will spark their imagination, and it is such a great thing to see and be a part of. Definitely a STEM product, and just hours and hours of good fun.
Review: Solid choice for toy - Best gift - asked a (grandpa) friend the best gift (longest-lasting across age ranges) he’d given to his grands and he said Blockaroos. He was right. We brought them over to my 90yo Grandma’s house and she played with them just as much as my 3yo son did. Love that they can be a bath toy too.

Bought these for my granddaughter and she loved them. So easy for her to play with and use her imagination since they are magnetic. She even used some to make a necklace. Years of enjoyment for her. Worth the investment!
