Magic Sea Urchin Boys (12 pieces) Will be shipped in a bag with simple packaging. When in use, even if dust or lint gets on them, they can be repeatedly used by simply rinsing them with water! I used them to make toys in plastic bottles, but my child's interest has passed, so I am selling them. I will take care to pack them in a clean condition, but due to their nature, lint tends to adhere easily, so please understand this point.
