retractable earplugs

RFQ Details

We are a company who are looking for a manufacturer of retractable earplugs without the earphones, we only want to buy the plastic thing so that people can put their own earplugs in it, and when they use them they can pull it out and when they don't it pulls the plugs back in. Sort of like mechanism used for a vacuum cleaner where you push a button and it pulls in the cord. It has to be a device that can be put on the cord of the earplugs. It should be small and cheap and easy to use. If you think you have something we can use please contact us a.s.a.p.
