Do Cloth Wristband come with Secure Closures?

There are 2 types of wristband closures available: 

Non-locking: This is a small black bead with enough tension to not fall off the band, but you can slide it up and down so that they’re removable and reusable.

Locking: This looks the same, however, it has a fixed lock inside of the bead that prevents it from being moved back down the band once set in place.
