DYZDDouble Hole Plastic Cord Locks End Spring Stop Toggle Stoppers Multi-Colour (10PCS, Grey)

I was a bit surprised at how small these were...the description is a bit misleading..I believe it gives the dimensions for the whole piece not the holes...you can get a piece of 8 mm Paracord through the hole only if you melt and taper the end to a point. This was not a deal breaker for me though...they hold well.I have been using them on the masks I have been making during our covid pandemic. I sew Paracord into the mask as straps and use these cord locks to make the mask adjustable to fit tightly to the face.

I bought these for general use with paracord, but getting the cord to fit into the holes required a bit of effort. I first had to re-melt the tips of my paracord changing the shape from a hard blob to more of a cylindrical shape. Second, I briefly applied heat to the cord half a inch in from the tip. This made it the cord stiffer, which makes it easier to thread into the holes. This isn't the worse thing in the world, just minor inconvenience. Once I had the cord lock on, I notice that the spring tension was a kind of soft. For most light applications I feel that this brand of cord lock would work fine, but in this particular instance I was using the locks on a Nalgene bottle handle I made. Holding the paracord handle and shaking a full bottle of water was more than enough to push the lock back. If this were strapped to my bag or body and I was running the bottle would have surely fallen off. I decided to just add another cord lock which made a significant difference. Shaking a full bottle of water with the double lock moved the locks a lot less making me more comfortable using this with my bottle handle. In the future if I were to do more projects that require the cord to hold gear or bear loads, I wouldn't choose these locks. For projects like cord bracelets or to replace cinch cords locks, I feel these would be fine.

These did fit my laces of running shoes perfectly and they stayed tight while running, I took the picture after a 2.5 mile jog, I did not have to tighten them once.I have Brooks running shoes which come with smaller laces, these may not fit larger laces, but they work great with these laces.

To Small to handle with the fingers, and not enough Tension on the Laces, They get loose easily

Definitely like the size, not too big or weighty, not too small (actual size is 1/2" across, 5/8" top to bottom, 1/4" thickness) Comfortably squeezes to open/release. 1/4" elastic and shoe lace ties thread through double holes.Using primarily for face masks (on upper head ties, bottom ties get , well, "tied." The "nurse" and others II make masks for are very pleased.

These are ok. For a pair of sneakers shoelaces it works but they are not particularly strong.

I bought about a dozen twill drawstring shorts from a local big box store, try as I might they wouldn't stay tied, so they wouldn't stay up on my waist. These little drawstrong toggles are perfect for keeping those shorts up.

i didn't like their holding power.they were only designed for paracord..i was hoping for multi use.
