I will accommodate your requests. ◎ About AirTag Some commercially available AirTag cases were larger than the photos, or the material was hard, and it seemed like it would be uncomfortable for the cat's neck. Therefore, after considering a case that is as small as possible and made of a soft material that won't burden the cat, this shape was created. 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 the AirTag. The photos have not been adjusted or processed for the size of the case. My own cats have been using them without any problems. ◉ Since these are handmade, the finish is not as perfect as a mass-produced product. I make them with safety in mind for use, but there may be slight imperfections such as uneven stitching or misalignment of fabric layers. Please understand these points before purchasing. ◉ Shipping will be via standard mail. Please note that delivery times may be extended since Saturday deliveries have been discontinued.
