Review: Pretty Colors and Great Quality - So beautiful. Perfect for toddler hands and to play with on a windowsill.
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.
