Luco Wooden Blocks in exchange for honest review from Giveaway Service. I liked the wooden blocks because they was solid and durable. My kids can not break these. Another thing I liked was blocks are one of Kalen's IEP/ARD goals to improve fine motor skills.
I did have to help him connect the pieces together. He also likes placing the blocks in the bag, dumping it out, and putting them back in the bag.
The kit comes with 65 (total) rectangular pieces, h shaped pieces (vertical and horizontal), and t shaped pieces, plus a carrying bag. The blocks also come in a colored version. The blocks are eco-friendly and unpainted. The blocks are made from rubber wood.
You can purchase the blocks on Amazon using the link above. The blocks are prime-eligible.
