Nite Ize Gear Tie® ProPack 32 in. - 6 Pack - Assorted

i thought the 'knobs' at each end would catch things in my bag and untwist. they did not. I thought the 3 inch would be too short because they wouldn't have enough length to twist multiple times. it did not stop it from performing. these things are strong. a simple half-twist, just hooking the other side is all it takes to secure my cables. In the picture, the blue cable wraps around the end once then the two ends can go around the bundled cable. This allows me to unravel my cable without the wire tie dropping off. It is so secure it doesn't even slip. Definitely a great decision to go with this product!
