Solid polished brass belt loop that matches my belts. Not essential, but a great way to tidy up loose ends.
This is a single 'keeper' loop but you can have as many as you like 'cos everyone loses them... Just sayin'...
If you don't want to spend the money on solid brass, you might want to try using hair elastics - much cheaper and they work pretty well. Ugly though...
Have a wonderful day.
