This tape is terrific. I use it to tie many things. Sticks with great strength. Beats 3M.

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.
