I have various other items for sale, please take a look here ➡️ If you have any questions about combined shipping discounts, additional purchases, or selling individual items, please feel free to comment. Due to the thickness being at the limit, I will put it directly into an envelope and use simple packaging. Thank you for your understanding.
