This is an "Osiris the Sky Dragon" Ultimate Rare card from Yu-Gi-Oh! QUARTER CENTURY CHRONICLE side: UNITY. Since I've been storing it in an inner sleeve from the time I obtained it, I believe it's in good condition, but it's been stored by a layman and is a layman's assessment. There is some warping due to humidity. No price reduction, instant purchase OK. I plan to ship it via Yu-Packet (Yu-Yu Mercari Delivery Service). I will keep it in the inner sleeve, put it in a larger sleeve for double sleeving, package it according to the procedure in image 5, seal the envelope with tape before shipping, write "Trading Card" as the item name on the shipping label, and send it.
