ARU Hirsch Glue
ARU Hirsch Glue, made from starch, is mostly used in making leather items. It's great for building shoes, especially for sticking and strengthening parts like the counter heel and toe puff. If used too early, you can dissolve it with water. But because it's not very flexible, it's best for temporarily sticking leather parts before sewing. You can get it in 600g bottles.
