Model Number: X8274 or M82 Recommended Laptop Size: 36.1 mm x 23.6 mm x 2.4 cm Inner Dimensions: 37.5 mm x 24.8 mm x 2.4 cm Outer Dimensions: 39.3 mm x 27.5 mm x 3.6 cm 【Shockproof & Waterproof】 Featuring an EVA hard sleeve and an upgraded shock-absorbing pad layer inside, this case protects your laptop from accidental collisions and scratches when placed in a backpack or suitcase. The Smatree storage case is made of durable 260G nylon, which is more water-repellent and abrasion-resistant than regular nylon. The laptop sleeve case can be washed when dirty, so you don't have to worry about water splashes. I am selling this because I purchased it new and realized I ordered the wrong size. The outer box is not clean as the shipping label was directly attached to it. However, the contents are in good condition. Please check the length of your laptop for the size. Please also refer to the photos of the outer box, which also show the dimensions. (It is recommended to refer to the recommended laptop size.) I will wrap the outer box in bubble wrap for shipping.
