Thank you for viewing. This is a listing for a set of two titanium hook-type keyrings. The weight is only 5g, and the product size is shown in the second photo. The hook type allows you to hang keys, keyrings, etc. on belt loops as shown in the sixth photo. Also, since it is made of titanium, it is rust-resistant, durable, and lightweight. This is a great value set of two, so you can use them separately depending on your needs. How about it, titanium lovers?
