I love Rubiks Briks Brand. Second time purchasing from the. The shipping was fast. The letter and number tiles only for to the small peg side. But on the other side you can use bigger blocks and they stick perfectly. The picture show that you can use mega blocks, strictly Briks and LEGO duplo blocks and they all fit perfectly. Smaller than I thought but definitely a decent size. Definitely hours of fun not only with the tiles but also with the legos. Definitely recommending this product.

Soo small! From the picture it looks larger.
