Solid polished brass belt loop that matches my luggage straps. Not essential, but a great way to tidy up loose ends.
This is a single 'keeper' loop - for a pair of luggage straps you need two! 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.
