Fabric case for Apple AirTag ◉Material: Cotton, Hook: Metal Size: Approximately 3.5 cm wide, 3.5 cm long Color: Japanese pattern, Pink Commercially available AirTag cases often come with unnecessary collars, or the cases are larger than the photos and look uncomfortable for cats. Therefore, I created this fabric AirTag case, aiming for a small, soft design that won't burden cats. ◉Attachment is easy: simply sandwich your existing collar (approximately 10 mm wide) and secure it with the hook. Have you ever had trouble finding your cat? By attaching an AirTag to their collar, you can use your iPhone to locate them. You can also make the AirTag emit a sound to pinpoint their location. ※AirTag and collar are not included. Please refer to the AirTag manual for instructions on how to use it. The photos have not been adjusted or processed to alter the case's size. My cats use them without any problems. ◉A collar is not included, so please use your favorite collar. As this is a handmade item, there may be slight variations in size and shape. ◉Shipping will be via Mini Letter. We are using Mini Letter to avoid price increases due to postal rate hikes.
