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, as a result of considering a case that is as small as possible and not made of hard material so as not to burden the cat, this shape was created. By attaching the AirTag to the collar, you can use your iPhone to find its location. You can also make a sound from the AirTag to pinpoint its location. Please refer to the AirTag manual for how to use the AirTag. The photos have not been adjusted or processed for the size of the case. My cats have been using them without any problems. ◉ Since they are handmade, they are not as perfectly finished as mass-produced products. We make them so that there are no safety issues when using them, but there may be some slight distortions in the seams, misalignment of fabric overlaps, etc. We appreciate your understanding. ◉ Shipping will be by regular mail. Please note that delivery days seem to have been extended since Saturday deliveries were discontinued. Please feel free to ask if you have any questions.
