This is the 【Collar×Malice Character Song (First Press Limited Edition) 1-5】 set. I purchased these upon their release and have stored them after listening to them once. In my amateur opinion, the condition is not bad. All of the keychains from the first press limited edition are unopened. Please check the images for the items. *Also, I am hesitant to sell these, so I will not sell them individually. Regarding packaging and shipping, I plan to use waterproof measures and shock protection, and ship via Rakuraku Mercari (in a cardboard box).
