I periodically buy a pack of Size #64 Rubber Bands at Staples and distribute them to the various areas in my home where our chargers and other small appliances with cords live and intertwine their long electrical cords. I hate dangling or intermarried cords but I can't keep track of the tiny black wires or the hook-and-hold tapes some come with to keep the cords wrapped. Your rubber bands solve the problem. They are easy to find easy to put on and keep the cord rolled up either around or coiled beside their device. They are reusable and inexpensive. Don't stop selling them.
