I bought this intending to use it at work, but it was too small for me, so I never used it... I've just been storing it, so I'm putting it up for sale. Material: 100% Recycled Polyester Size: [Width] 10cm [Height] 16.5cm [Depth] 4.5cm ● Material Characteristics: Made with "RENU," 100% recycled polyester, which is made from used clothing and leftover fabric from factories, considering the environment. Lightweight and tough material. Perfect for daily use, and also easy to take outdoors. ● Comes with a buckle (Velcro) that can be easily attached to a shoulder harness without a carabiner. ● Velcro is also attached to the top opening! ● The front has a mesh window for easy viewing of the contents. ● When not using the shoulder strap, you can store the strap in the inner pocket! Please contact me if you have any questions! Thank you.
