I have a lot of Disney pins I keep on my backpack, so these are perfect to make sure I don't lose any pins I'll while at the park. They are very secure and definitely lock into place after they're on the pin.

These are great for keeping your thread contained and untangled!

These are a great to have. only suggestion is be careful with the locking pin it does fall out more frequently then we would like.

Pretty neat little pins. The pins are not 100% trust worth with locking, so be careful. But my husband loves them and has it hanging in his truck.

These locking pin keepers were great. I was worried about losing my pins on my jean jacket, but these locks keep them secure. I would definitely order them again. My only complaint is that there were no instructions on how to assemble the locks. I figured it out but would have preferred some instruction.

Nice concept to keep from losing these tiny pieces.

Pretty much every pin I buy that doesn't come with the even-worse-made butterfly clasps come with a worse version of this. While these do the job for the most part, they've proven sometimes unreliable at keeping pins on my messenger bag. Nearly lost a pin as I got out of my car (the backing went missing for 3 days til I randomly found it in my driveway).

If the pins are never touched, I'm sure this works fine, but since my pins are on my bag, they'll be moving around a bit and might take (small) amounts of force. If you're putting pins on your clothes or hats or just storing your pins, I'm sure these will work just fine.

As for a replacement, I already have a package with Outee's 40 metal pin backings coming in a few days. Hopefully those will ensure the pins never come loosened on my bag.

I usually have several projects going at once, so I use a lot of pins at one time.  This is a lot of pins.  The heads are well attached and the pins a smooth.  There are about 5% of them that have less than sharp (dull) points and are hard to get thru closely woven material.  I would order these again.

Good little pins.  This amount will probably last me the rest of my life!  (Yeah I'm old)

Purchased these to be used with my locking pin savers to add a little more spacing so pins don't protrude out. Perfect size and seems durable.

These little pins are so convenient.  I use them to pin up Drs. appts., new recipes, notes of all kinds.

These are the perfect size for using as a substitute for pinning. I love them. The decorative tin keeps them organized. I on;y wish I had bought them sooner. They really hold things tightly.

Our ladies don't like sticking pins in their clothing and the hanging badges get in the way.  This is the perfect product for name badges.

Perfect for keeping track of where you been and where you want to go. Once you put a pin in the foam, there is a hole so make sure you definitely want to pin a place before you do it!
