These are great for keeping wire on the spool. Yes, that's actually a problem, and yes, these solve it. 

Beadalon Spool Tamers are long and adjustable, and will fit around the large Kidney Puncher spools! They feature a sewn loop to hold while pulling out wire, but this can be removed if you prefer a large, loose fit around your spool. The band is elasticated and adjustable, and the mouth is rounded so your wire won't snag while it's feeding through.

Another great way to use these spool tamers is to thread them through the center hole of your spool.

Each pack contains 3x Beadalon Spool Tamers.
