Secure and reliable - no more lost pins
I bought these to secure pins on a lanyard, as I was finding the standard backs would fall off quite easily with regular movement (and being thrown in a bag). I had some really nice pins I didn’t want to risk losing. These are solid metal backs with a flat profile, and they feel much sturdier than standard ones. They also come in a small tin, which is great for keeping the extras organised. They’re very easy to use - just remove the original back and push this one on, and it locks into place straight away. Since switching to these, all my pins have stayed securely attached, even after a couple of years of regular use on a lanyard. I’ve also used them on backpacks and straps with no issues. They worked with all the pins I own. They can be a bit tricky to remove, but that’s kind of the point - they’re designed to stay put. With a bit of effort, they do come off when needed. For the quantity you get, they’re excellent value. I still have some left and keep them stored in the tin in a drawer. Overall, these are a really worthwhile upgrade if you wear or collect pins and don’t want to risk losing them. I’d definitely buy them again.

Just what I needed
Definitely recommend, they are so strong I was able to lift my backpack by a pin and the back did not come off. I think 30 for this price is absolutely wonderful, I now have a ton of pins on my backpack, on my lanywards and still have spares left. The backs fit all my pins, they may need a bit of a wiggle to fit at first but they are 100% secure. Would recommend to anyone

Work very well.
I was forever losing pins because the backs fall off, I lost a rare one recently which was very upsetting and spurred me on to look for better backs. These are great! They are very easy to put on but take some effort to get off, so they won't easily fall off or be knocked off by mistake. I haven't lost a single pin since using these. They keep the pins in place also, so they stay where you want them to and the right way up! Very happy, just wish I'd got them sooner!

Easy fit pin backs
Well made, easy to fit. Good replacement for butterfly pin backs. Will put them to the test on my leather jacket.

They work a charm. Safe for use on pin badges in a school.

Perfect solution for keeping precious pins
Perfect solution to pin loss! I'm not a pin collector as such, but I have gathered some along the way and now have them only on one bag strap - I've lost quite a few and caught others just before they fall - and I wear this one with trepidation! But NO MORE! These backs really are brilliant - they don't budge! And in a handy tin so you don lose the rest 🙌🏻 Thumbs up all round

Effective, well designed.
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.

Sehr gut und sicher
Sehr gut von der Verarbeitung, es passt nicht jeder Pin aber 90%! Manche Pins gehen schwer rein aber das liegt am Pin! Sehr sicher!

Excellent quality - works great!
The Mudder locking pin backs are high quality and work great. No worrying about your favorite collectible pins falling off and getting lost. I use the pin backs on my collection of Disney pins that I decorate my jean jackets with. The pin backs connect to the pins easily and stay in place. It takes time to learn how to remove the backs, but with a little practice it will become easy. Push down on the flat part of the pin back, and squeeze the raised part and then pull up on it. The metal storage case that is included makes it easy and convenient to store unused pin backs, as well as the plastic pin backs that come with Disney pins.

Véel te kleine opening! Meeste standaard motorcycle pins passen hier simpelweg NIET in...
Ik heb tientallen pins zowel op m'n battlejack als op m'n lederen motorvest. Dit zijn pins met een staafje van ongeveer 1mm dik. Deze pinlocks zijn véél te klein en geen enkele van m'n pins past in het gaatje van de lock. Ze moeten dit in de omschrijving veel duidelijker vermelden... Weeral een retour die kon vermeden worden door correcte informatie aan te leveren in de productomschrijving :-(

Klips pins
Stufo delle originali klips per le pins delle mostrine della mia divisa ho cercato delle alternative ho trovato queste delle quali sono veramente soddisfatto ottima tenuta e per toglierle addirittura a differenza delle altre si fa fin troppa fatica per chi come me indossa la divisa le consiglio
