I purchased this on Mercari about six months ago and used it a few times for a short period, but I'm selling it as I don't think I'll be using it anymore (*^^*) As I didn't purchase this item from a store, I'm not considering the "Authenticity Guarantee" service ( ¨̮ ). Also, while I believe it's in good condition, it's a used item, so please refrain from purchasing if you're looking for something perfect (⁎ᴗ͈ˬᴗ͈⁎) I plan to ship via Yu-Packet Post. Please feel free to comment if you have any questions (*ˊ˘ˋ*)
