Harley Benton StrapMaster Pack1

Decent for the price. Unfortunately, the red ones are not red, at least not the ones that I have received. They are more magenta/raspberry in colour which is a shame so once I got this set specifically for the red ones. Another “issue” is that the rubber used is quite thin and soft, which resolves in the ring deforming into concave like shape which is not aesthetically pleasing. Function wise there’s nothing wrong with them, they do work and stop the strap from falling off small strap buttons.

They are easy to install, work great preventing slip even with old, worn out belt loops, but tend to eventually screw out the strap buttons on guitar.

I suppose I could've paid more attention to the pics. These are almost twice as big as the Grolsch/Fender gaskets so they are very visible.
Very thin and soft, they slip out of the strap button too easily. And the red ones are actually pink.. Good thing I have a shell pink bass!

Buy the Fender ones. Much sturdier.

Excessively wide! With a thick leather belt, such a thick ring fits very tightly. Not good

These may have smaller holes compared with the Fender ones, but they are more elastic.

For the price is a no-brainer but I still prefer the Fender ones for safety reasons.
