I bought them with the intention of using them, but I ended up not using them, so I would appreciate it if someone who can use them would take them. I took them out of the bag to take photos. These are items stored at home. Please refrain from purchasing if you are sensitive or concerned about minor details. Thank you for your understanding before purchasing.
