Chums eyeglass retainers were invented by a Grand Canyon boatman who saw a need for stylish and functional eyeglass retaining product line. Based in the US, Chums continues to be the innovative leader. Man of Rubber is proud to have been chosen as Chums very first sales rep back in 1984.You can also customize your Chums to commemorate a special event or your business name and/or logo. Minimums do apply and there are some specific art requirements that we would love to speak to you personally about. Certain retainers can have a silk screening done to the fabric of the retainer itself and others require a special “dome” to be added to the slider that adjusts it out.
