This is a Beckmann street light. I bought it a year ago and only used it once, so I'm selling it. It's in almost new condition, but it's still a used item. Please understand this before purchasing. To prevent any trouble, I do not accept any claims or returns. This is a 22-liter model that can be used in all situations. It's made of environmentally friendly and water-resistant recycled polyester material. It has a compartment with ventilation holes for storing shoes, towels, etc. It also has a mesh cover for storing and securing helmets, balls, and outdoor gear. The back and shoulder straps have durable, thick, and breathable padding. It has a separate protective compartment that can hold a 15-inch laptop.
