This bag on wheels is Zee Ultimate Carry All (ZUCA).
Interior features enough room to hold figure skates/dance shoes plus accessories. Side pockets both inside and out provide extra storage space. Oversized urethane wheels make for smooth, easy rolling while a second wheel higher up on the frame makes it easier to climb curbs and stairs. The lightweight, durable aluminum frame doubles as a seat. Wheels sport dynamic flashing LEDs for night visibility.
