This is a protective seal for covering addresses on postcards, which was previously included in a DM for a coach's customers. I saved it because the COACH signature was cute and I couldn't throw it away. ※This item is about 20 years old※ Although unused, it is a paper product, so it may have deteriorated over time even if it's not visible. Please refrain from purchasing if you are looking for a perfect, pristine item. Please check the condition carefully to prevent any problems. This is a very old item. Since this item is not widely available, how about it for those who enjoy rare and retro collections? I will send it with cardboard reinforcement on one side. Thank you for looking.
