Since these are used items, please refrain from purchasing if you are concerned about minor details. I inspect items during packaging and keep photos as evidence.

Please ask any questions you may have. ☆ If I don't notice your comment or forget, please kindly comment again. ☆ No price reductions. I lower prices daily or weekly, so please consider purchasing at the listed price. ※ I will send a shipping notification after dispatch, so I will not send a separate message. ☆ Please refrain from purchasing if you are concerned about wrinkles, as I will pack items compactly. Clothing may be packed in Mercari's original compression bags. ☆ Cosmetic boxes may be folded for compact packaging. ☆ Returns and cancellations are not accepted. ☆ Returns are not accepted to prevent product substitution. ☆ Please do not purchase if you are a stickler for details or are overly sensitive, as these items are stored at home. ☆ Some new, unused items may have had their price tags removed.
