水晶色彩堆疊杯

My toddler spends ages stacking these and then watching how the colors blend when you hold one up to the light. The see-through plastic feels sturdy enough for daily play, and it's been great for talking about primary colors. Really happy with how much learning comes from something so simple.

The way the light hits these cups when you stack them is honestly mesmerizing, and my kids have been totally absorbed trying to mix the colors by holding them up together. They're light and easy for little hands, and I love that they're sneaking in some building and problem-solving while they play.

The cups are nice and colorful, but the light they let through doesn’t really help with color mixing as described. My kid enjoys stacking them, though the plastic feels a bit flimsy for the price.
