Buyers Beware!

Once you've used these, you cannot see yourself without them. These are movable, reusable, and a must-have for organizing and uniting your cables. You will not go wrong with these. Very affordable and well-made.

Great for cords and cables
Size: 6inches-60PCS
Works well to control excess cords and cables. Easy to use and the adhesion is good . I even fastened two together to attach a bundle of cord to a table leg.

Nice and well made
Size: 6inches-60PCS
I like these inexpensive cable ties to reuse. Cell phone cords, or lamps cords work great to get them buttoned up crisp.
