Gutenberg Paper Glue
This is similar to what we know in the USA as "rubber cement", except that using the car analogy of a Chevy vs a Rolls Royce fits. Gutenberg makes its paper glue using real "gummi arabicum" (pure natural gum made from the sap of acacia trees) with only water as a solvent. It's appropriate to use it on even the most delicate papers. Each refillable applicator contains 2 oz (by weight). The Refill (not pictured) contains 10 oz.
