Chalk Bag / Climbing Pouch

This is a chalk bag made by TIME WALKER, purchased about 20 years ago (Photos 1-3). I didn't use it as a chalk bag, but rather as a small item holder for energy-boosting candies during trekking. I only used it a few times, so there are no noticeable stains or scratches. The diameter of the circular opening is 7cm, and the shape is not cylindrical but triangular when viewed from the side (Photo 4). The height from the opening to the bottom is 10cm. It comes with a belt loop and a small aluminum carabiner.
