tomtoc Travel Bag Business Backpack Multifunctional Travel Business Trip Black Carry-on Thank you for viewing. I have only used it once, but I am selling it because it doesn't suit my needs. It is a used item, so please understand before purchasing. I hope you can judge the condition from the photos, but Please feel free to contact me if you have any questions. Also, please note that it may be folded up small for shipping. Thank you. Below is an excerpt from the product description from the sales site: [40L Large Capacity & Carry-on] This is a 3-way backpack with a main storage compartment, a PC storage pocket, and a front pocket. The 40L main storage compartment opens like a suitcase, making it very easy to take things in and out, and can store enough clothes for 2-3 nights to 4-5 nights. If you have less luggage, you can make this backpack more compact with the side buckles. Carry-on size: 52cm x 33cm x 23cm. Note: Due to being handmade and differences in measurement methods and conditions, there may be slight differences in size and weight. [Innovative Design & Convenient for Security Checks] The hidden zipper under the front pocket allows access to the main storage compartment, making it easy to take things in and out and organize your luggage at any time. The PC storage compartment, which can store a 17.3-inch PC and a tablet separately, can be opened 180 degrees, so you don't have to take out your PC during security checks, allowing for a smooth process. [Ease of Use] It uses reliable YKK zippers, which are durable and very smooth and easy to open and close. The zipper of the main storage compartment can be locked with a padlock, which is a security measure for overseas travel. The water-repellent outer fabric can be cleaned by simply wiping off water, and is perfect for light rain protection. The top and side handles, and the suitcase belt on the back make travel more comfortable. Color: Black系 (Black-based) Accessories: None Stains/Tears: None
