Thank you for viewing. This is an SSK silent caster bag (travel bag). I used it for several years to transport umpire equipment. I believe it's the model just before the current model. The approximate external dimensions are 60 (100 when the handle is extended) x 40 x 30cm. A shoulder strap is included. The large, silent casters are strong enough to handle steps and can be pulled with little effort. It has ample capacity, easily fitting a mask, protector, leg guards, two pairs of shoes, a full uniform set + a jumper + small items. Also, the main pocket has a compartment with a divided entrance (next to the base of the pull handle), so you can separate dirty items. Overall, it shows signs of use, and as shown in photo 6, there is a tear in the bottom, but it's in the part with the hard bottom plate, so it shouldn't be a major issue. Especially if you want to use it in a car and drag it around at the location, it should be almost no problem (I used it dragging it around on trains and buses). Due to its size, I will ship it in simple packaging (the same as when I bought it new). I have newly registered to organize my household items. I may be unfamiliar with some things. Please be aware of this.
