## Description

Acrylic Rainbow Stacker

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.
Review: These Are Amazing! Worth It! - These are just as amazing as they seem. The stock photos are a true representation of what you get. These are some kind of acrylic material, yet they feel and sound like glass in your hand. They do scratch but it's minimal and you really do have to try to scratch them or like scrub them on a gritty floor. They appear for the most part flawless during normal play. They arrive absolutely spotless and it's easy to keep them that way. The colors are vibrant and clear. I find myself playing with these blocks, they are so mesmerizing! I got them for my daughter's second birthday as a gift and I have no regrets whatsoever! If you're deciding what blocks to get stop your search. These are the ones!
