Design process

step 1
Must smooth out sharp corners before use. Otherwise it will damage the cable instead of protecting.
step 2
slide in the cable through a gap. You might need to apply some force to widen the gap.
When you pull the plug from a device, you should grab the protector by the clip side, so the protector won't come off the plug.
