This is a nylon bag with casters and multiple storage pockets. It's a collaboration model with Riedell, a long-established American skate brand. I bought it in LA about 10 years ago, and it's not available in Japan. https://riedellskates.com/ I haven't used it much, so there are no noticeable scratches, but due to aging, the spacers are cracked, and the 100MM wheels don't light up. I replaced the spacers and bearings, so they spin smoothly. There are two wheels on the side, but they're useless and make it heavy, so I removed them. I have the screws, but the removed wheels are missing (^^; - Brand: ZUCA (Riedell model) - Color: Black - Storage Pockets: Multiple pockets - Carry Type: With casters - Material: Nylon The wheels don't light up because the spacers are cracked. Bearings have been replaced. Thank you for looking.
