These airtag keychains are 100% handmade in the UK using full-grain vegetable pull up tanned leather, Mad Dog range. They are durable and secure due to the wrap around design that weve created, with no window holes. It will make a very nice present for your boyfriend or dad, or as a 3rd wedding anniversary gift for him. We ensure a long-lasting case due to high quality materials used, most of them sourced localy from small family run businesses. Being a natural product this vegetable tanned pull up leather case will age beautifully, time will only add character to it and the leather will get a very nice patina from everyday use. Buying a product from BearLeftLeather you are not helping one, but many small local businesses. Matching accesories and other colours available in the shop. Thank you for choosing to have a look at my products and I hope you like what you see. Yours truly - Alex the creator
