[Apple Tag Design]: AIRTAG dog collars are designed specifically for Apple tags, and they are a perfect combination to keep you updated on your pet's location at any time. We have an aviation label holder and a silver bell on our collar. Let you find it through sound. (Note: AirTag is not included.) [Safety and Comfort for Pets]: The Airtag case is made of soft silicone, non-toxic and environmentally friendly, and is printed with a reflective and cute pattern to maintain high visibility in the dark. When forcefully pulled, the broken buckle can be easily released, effectively preventing suffocation accidents caused by forceful pulling on the neck. [Adjustable collar size]: Adjustable in length, suitable for pet neck sizes of 19-32cm, with a width of 1cm, suitable for most small animals such as cats, dogs, and kittens. To choose the correct size, please measure the comfortable position of the cat collar before purchasing. [Wide and easy to use]: The Cat Airtag collar has a waterproof Airtag bracket. Put the Apple Airtag into the cat collar bracket, and then you can use your iPhone to accurately know where your pet is to ensure its safety. The sliding design can be widely used for cat, dog collars, and anything with straps. [What you got]: Cat collar with Airtag Holder * 2.
