This is a building block set featuring cute sea creatures, allowing you to learn while you play. There appears to be some dirt on top of the dolphin, but it hasn't been taken out of the plastic. I believe it's from the cardboard box inside. If you're concerned, I can take it out and dust it off before sending it. - Product Name: Sparkling Eyes Aquarium Building Blocks - Set Contents: 10 types in total - Target Age: 6 years and older - Manufacturer: YELL Co., Ltd. - Size: Approximately 6cm for each character Although it's new and unopened, it has been stored at home, so please refrain from purchasing if you are sensitive to this.
