This is a magazine supplement from marble. It's light blue. It measures 27.5cm wide x 20cm long. Since it's quite large for a pouch, I sewed D-rings on the sides and used it as a shoulder bag. The fabric is a Moomin-patterned synthetic leather, but it has a thin sponge inside, making it soft and resilient. It's completely waterproof. The strap is removable, so it can be used as a second bag or pouch. I was satisfied with the modifications and rarely used it. I hope someone will find it useful.
