Colorful character yo-yos made of silicone that light up. - Model Name: Flash Monster Yo-Yo - Colors: Blue, Green, Yellow, Pink - Material: Silicone - Design: With characters - Light-up Feature: Equipped with LED lights Thank you for viewing. This is a set of 3. The green one lights up, but the yellow and pink ones have dead batteries. It's also unknown how long the green one will continue to light up. They aren't fully inflated, so you might want to add air. The face on the pink one is slightly peeling. Please check everything in the photos. Because they are made of rubber, there may be some fine dust, but please understand. I had kept a new one, thinking I'd give one to my child if one broke, but they were able to play with just one, so I'm selling the remaining set.
