The natural glue made with potato starch, rubber tree gum, and water is packed in an antique like glass bottle with aluminum lid.
The Gutenberg Gummier Stift Stick does not attack sensitive paper and has proven to be economical office adhesive, suitable for daily use at home, in the studio and in operation for 50 years. Some people describe that "using this bottle is like using your own fingers to apply the glue." It's hard to understand this wonderful experience unless tired in person.
