I used this as a carry bag for skis, and it was convenient for carrying ski boots. The material details are unknown, but it's constructed with parts that seem like hard plastic and parts that seem like nylon fabric, making it a sturdy build. The plastic and nylon parts can be detached with a zipper. The hard plastic part is divided into two compartments internally, and cannot be removed. The nylon part expands greatly, so it can store plenty of thick winter clothing, and it was also useful for travel other than skiing. It's well-used, so there are scratches and scuffs overall. 【Size (approximate)】 ※The shape is not square, and the nylon part is measured without contents. Please check as a reference. • Height: Approximately 74cm (including casters) ※ When the handle is extended: Approximately 86cm • Width: Approximately 46cm (bottom) • Depth: Approximately 20cm (plastic part) • Caster diameter: Approximately 8cm 【About the condition】 There is a small hole on the left side when viewed from the front (see images 17, 18). Since it was originally a type without a lock, I made a hole and used a commercially available lock. The number is unknown, so the lock has been disposed of.
