Fabric case for Apple AirTag ◉ Material: Cotton, Hook: Metal Size: Approximately 3.5 cm wide, 3.5 cm long Color: Japanese pattern, Red 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 been worried about not knowing where your cat is? By attaching an AirTag to the collar, you can use your iPhone to find their location. You can also make the AirTag emit a sound to pinpoint their location. ※ AirTag and collar are not included. Please refer to the AirTag instructions for how to use it. The photos show the case without any size adjustments or processing. My cats use them without any problems. ◉ The collar is not included, so please use your favorite collar. Due to being handmade, there may be variations in size and shape. ◉ Shipping will be via mini-letter. To avoid price increases due to postal rate hikes, we are shipping via mini-letter. Delivery time is the same as regular mail. Please feel free to ask if you have any questions.
