This is a white pochette from Ami no Mise Oyama. It is new and unused. It has been stored in the condition shown in the second image. It is an Ami Pochette Elizabeth Collar. From the time of purchase, there is a part like the one in the third image. I purchased it at a pop-up shop, but I have other colors and don't use this one, so I am selling it. The fourth image is borrowed. Ami no Oyama Naoki Oyama Thailand
