500 ml of liquid dosa for sizing paper
From Japan.

Mix of Myoban and Nikawa cow skin glue
In Japan, the dosa liquid is used in conservation or is used as a sizing applied to a paper for Nihonga or calligraphy, to prevent the inks from bleeding into the paper.
Because myoban is naturally on the acidic side, the pH of the dosa is slightly acidic.
Product will freeze and subsequently become unusable if subjected to frozen climate.
500ml will comfortably cover about 5 sheets of 25" x 38" size papers (will vary depending on the desired effect)
Shelf life: approximately 1-2 years after opening
