    Works well even through lots of unfastening and refastening.

    This stuff is a necessity in my house. We use it for cord organization, keeping French doors and cabinets closed (toddler proofing), even on the garden hoses in the garage during the winter. This is holding up great even after removing dozens of times.

    bought for work and home
    Size: 1/2 Inch X 90 ft, Number of Items: 1
    I have tried several different rolls of velcro. What sets this brand apart is that it is thinner than the others I have used, so when wrapped around cables is not as bulky. It does grip as it should. As mentioned in my headline, I originally purchased this for work, so when I wanted a roll for home, I chose this one.

    Cheap tie for cables and hoses
    Size: 3/4 Inch X 90 ft, Number of Items: 1
    I just cut to length, then use a hole punch or ID punch to make custom wraps for cords and hoses. Pull the wrap through the hole after it goes around one cable, then wrap the coiled cable. Much cheaper than buying ties from the local discount hardware store.
