The Arctic Star style AS71-B-ASST-24 is the flat out ultimate best value price for a 17 inch classic designer inspired wholesale backpack for bulk back to school backpack purchases. With an incredible price, this backpack separates itself in many ways from the competition. This unisex backpack is made of 600D polyester and measure 17 x 12 x 6. The 17 inch height is the perfect height for all ages of boys and girls elementary, middle and high school. The 6 inches of depth here are the most important though as this is what helps store the most books, folders etc. Many competing bags have a depth of under 6 inches which is insufficient in terms of overall storage. This quality crafted bag also has a mesh covered handle, padded back, and padded ergonomic adjustable back straps adding to the overall comfort of the backpack whereas many competing bags have backs with no padding at all and thin straight line back straps! And to top it off we have used a top quality number 10 zipper which is the largest and strongest zipper available and adds to the durability and life span of the bag. You simply will not find this on a competing low cost bag. The 24 piece case contains 8 black, 4 navy, 4 charcoal, 4 royal, 2 dark green and 2 burgundy.
