The Lenovo 4X40N18009 sleeve case is a slim, lightweight protective cover designed for laptops with a maximum screen size of 35.6 cm (14 inches). Made of polyester and weighing 0.309 kg, the sleeve fits recent ThinkPad and other 14" notebooks to guard against dust, scratches and minor shocks while remaining easy to carry and stow in a larger bag.

Its polyester construction resists abrasion and helps shield the device from everyday wear. The monochromatic design provides a simple, professional appearance that complements business and casual use.

Suitable for

• 14" laptops and ultrabooks (maximum screen size 35.6 cm)
• Daily commuting and transport in a larger bag
