The 3,14BAN 25 × 35 cm sleeve is an upcycled laptop sleeve for 13–14" laptops, made from a durable advertising banner. The banner material holds its shape, stands up to everyday carry in a backpack or bag, and works as a protective laptop sleeve—taking on scratches, dust, and scuffs while you’re on the move, at the office, or studying.
Inside, there is a Reinventex lining made from recycled textiles (a non-woven felt-like material). It adds softness, reduces friction, and keeps the device in place so the laptop doesn’t shift inside the sleeve. This is especially convenient for those who often carry a MacBook Air 13, MacBook Pro 13, or compact 14-inch models (for example, Dell XPS 13/14, Lenovo ThinkPad T14, HP Envy 14, Asus ZenBook 14)—just make sure to check the dimensions.
Each banner sleeve has a unique print: no two upcycled laptop sleeves are the same, so you’re getting more than an eco-friendly laptop sleeve—you’re getting a 1-of-1 piece with its own story. The 25×35 cm format is made for everyday use: minimalist, practical, and focused on conscious consumption and responsible design.
Recommended maximum laptop dimensions: up to approx. 33 × 23 cm.To make sure it fits: check your laptop’s dimensions (length × width) in the specs—if they are up to 33 × 23 cm, the sleeve will fit comfortably.
Care: do not machine wash. Clean with a damp wipe or a soft cloth.
