Rich I Rich I LEATHER HELMET BAG・OFFICE CTHY This is the OFFICE size of the Rich I classic helmet bag. It can hold A4 documents and a 14-inch laptop, and I think it's a useful size, not too big and not too small. I've only used it once, so I think it's in good condition. The only included accessory is the shoulder strap. Below are the product specifications (quoted from the sales website): Width: 36cm, Height: 32cm, Depth: 10cm BODY LEATHER LINER COTTON - 100% TAPE ACRYLIC - 70% LINEN - 30%
