Therefore, we considered a case that is as small as possible and made of soft materials to minimize the burden on the cat. This is the result. By attaching the AirTag to the collar, you can use your iPhone to find your cat's location. You can also play a sound from the AirTag to pinpoint the location. Please refer to the AirTag manual for instructions on how to use it. The photos have not been adjusted or processed for case size. Our cats have been using them without any problems. ◉ This is handmade, so it is not a perfect finish like a mass-produced product. We make sure it is safe to use, but there may be slight stitching imperfections, fabric overlaps, etc. We appreciate your understanding. ◉ It will be shipped via regular mail. Delivery times seem to have increased significantly since Saturday deliveries were discontinued, often taking 4-5 days. Please feel free to ask if you have any questions.
