Review: Unbelievable - These are the coolest thing I’ve ever bought in my life maybe. We got them for our 4 year old but the whole family is obsessed with them. Absolutely crystal clear they are sooo neat to look through, stack, when you put them in larger colored boxes they make neat optical illusions and disappear-I can’t wait to take them outside in summer. We can’t wait to add more sets. These are not cheap at all but my gosh they are beyond worth it.
Review: Perfect size! - These are smaller than I expected but they ended up being the perfect(!) size for our little guy to load into dump trucks of all sizes, and stack, and play with creatively. They are so pretty in the sunlight! He loves the red one best!
