Opanchu Usagi's "Poor Thing!" cap set of 4. I'm selling these because I only know the character's name and don't plan to use them. The thickness is just under 3cm, so I plan to ship them with simple packaging: waterproof protection only, no bubble wrap. If you're willing to cover the difference in shipping costs, I can also pack them with bubble wrap, so please feel free to ask. If you have any questions, please feel free to ask in the comments section!
