The large zipper pouch is 25 cm long, 13 cm high and 11 cm wide. It’s perfect as a toiletry bag, as an organizer bag in your suitcase when travelling or, for example, as a utensil for smaller knitting or crochet projects.
You can simply “sprinkle” these into a seam from time to time. A piece of webbing with a belt loop sewn in the middle (seam facing upwards) would be perfect as a handle.
