after my other set of Jumper Cables go out . I buy the biggest set I could find , 20 Foot 2-Gauge Professional Jumper Cables and these be not cheap !!! I start to look for a bag to store these in , so I could keep they nice and like new . I find this one on Amazon and get it in . just Roll the Cables up , good and tight and have no problem put they in . bag be sturdy enough to keep they like new for many year to come . I highly recommend this bag !!!!!!!!!!
