I have a habit of attaching a hook-and-loop string to my towels.
These towel hooks come in very handy!
When I want to hook the towel to an S-shaped hook or a magnetic hook, this hook string is very useful.
You can also use the towel with the hook-and-loop strap on a carabiner on your backpack when you travel.
Once you know how convenient this is, you will never get rid of the habit of attaching a hook-and-loop strap to your towel.
