Color: Black Purchase date: June 29, 2022 Nordace Siena – Lightweight Daily Backpack It's sized to fit a 15.6-inch PC. https://nordace.com/ja/product/nordace-siena-smart-backpack/ I used it for commuting about once a week for about two years. There's some pilling on the shoulder straps, showing signs of use, but there's little shape distortion or damage, and it's in good enough condition that I feel it's a waste to throw it away.
