Any products that solve this problem? I can't find anything other than headphone/USB cable winders.

Problem: Wife's vanity has a pullout cabinet that stores hair dryer/flat iron/etc. Cables are a constant mess and get in the way of closing the cabinet.

Goal: mount a wheel on the side of the pull-out that the appliance cable wraps around that will automatically roll the cable back in when necessary. The other end of the cable is always plugged into an outlet in the cabinet.

Get some velcro cable ties. A 50 pack ranges between $4 and $8 for ties that are six inches or less (Amazon).

Use the remaining ties to straighten up your computer desk, A/V equipment, etc.
