Please be sure to read the profile. Thank you for viewing. I used it a few times and then stored it at home.

This tote bag is perfect for hobbies, travel, and business. ✅【Quick Pocket】 Designed with a magnetic pocket on the back for quick access and storage. It's large enough to easily fit any smartphone. ✅【Safely carry PC devices】 Made with sturdy fabric and thick cushioning. The PC holder uses brushed fabric to protect against scratches and impacts. The magnetic holder allows for smart insertion and removal, supporting comfortable PC work. ✅【No problem even in heavy rain! Super water-repellent design】 The water-repellent material and YKK water-stopping zippers prevent your belongings from getting wet even in sudden rain. ✅【Durable material for long-lasting use】 It uses 1680D polyester composite material, which is highly water-repellent, resistant to scratches and dirt, and more impact-resistant than nylon. Dust can be easily brushed off. It is durable and can be used for a long time, making it the best value for money. The "D" in 1680D (denier) refers to the thickness of the fabric. General bags are around 500D. ✅【Product Specifications】 ■ Product Name: Tech Tote ■ Brand: Zepiron ■ Size: Top 45/Bottom 39 x 31 x 9cm ■ Strap Height: 27cm ■ Weight: Approximately 770g ■ Color: Black ■ Material: 1680D polyester composite material ・ Zippers: YKK water-stopping zippers
