Crystal Acrylic Cubes Magic light-transmitting square, explore the law, enlighten the senses, let the children recognize a variety of colors, and guide the children to master the skills Review: Very Good Quality - These are so adorable! And the quality is great! They were very expensive (I bought two sets of 16 blocks) but I can see why now. I wish they had additional sizes and shapes, I would buy a whole collection. My daughter loves them, they’re a better size than the cubes- I was worried about the size since we have a 6 month old as well but these are perfect. I love the vibrant colors and the quality really is good- they haven’t scratched or anything. I will probably end up buying another 2 sets of 16 to add to our collection.
