Mudder Locking Pin Keepers Backs, No Tool Required (Silver, 30 Pieces)

These are the best pin backs I've come across. Both more straight forward to use and more effective than other 'locking' designs I've used (which often involved messing around with Allen keys). The flat interior surface is also less liable to scratch than the classic 'butterfly' pin back when pins are worn against the skin. These give me real peace of mind when wearing pins on bags/straps where they're liable to catch or fall off - definitely recommend.

Perfectly secure on my bag, feels stronger than super glue. I lost several pins before buying these and had to hunt them down and replace them because I was so sad. I just didn't want to lose anymore, but didn't want to keep them in the house either. These pins have resolved that. They just click on and you're ready to go, so easy. Recommended!

Works well with my pins (lock on easily) compared to those of which I've lost on numerous occasions in the past as the original keepers are flimsy and largely ineffective.

Only issue was they did not come in a useful tin like is shown in the advert. That said the items themselves are perfect.

Excellent locking pins, I was worried I wouldn't know what to do with them but it's pretty easy to figure out! I've tried pulling them off my bag but the pins don't move so it's pretty sturdy and secure. They fit my pins with ease. Definitely worth the money

I was forever losing the clips of the back of my badge. Bought these. Only ever used two. They have resolutely held on to the badge ever since. So in that sense their performance cannot be faulted. Good quality finish. No tarnishing. Big thumbs up!

My daughter lost a couple of precious pins… got these to replace the backs. Easy to push-fit and are extremely secure. Absolutely would recommend!

Great. Keeps in place. Easy to use. Good quality.
