What happens if the washi bag gets wet?

The washi used in Washika's bags is coated with a konjac glue layer, which prevents water from immediately penetrating the material. However, as it is not completely waterproof, some water may eventually seep into the surface over time. Even if water does seep in, the bag’s strength will not be compromised, nor will its shape deform. If the bag gets wet from rain, simply allow it to dry, and it will return to its original condition, ensuring it remains safe and reliable for use.

Will the washi paper tear with use?

The thick, hand-made washi paper used in Washika bags is exceptionally durable and distinct from ordinary Western paper. Its unique fiber structure makes it highly resistant to tension and friction, ensuring that it does not tear or wear down at the edges through everyday use. Unless subjected to sharp objects or extreme force, it will not develop holes or tear.

How should I care for my washi bag?

No special care is required. If the bag gets wet, gently wipe off the moisture as soon as possible and allow it to air dry in a well-ventilated area. This will help preserve the material's characteristics, ensuring it lasts for a long time.

What is "kakishibuzome"?

"Kakishibuzome" is a traditional Japanese dyeing technique that utilizes tannin extracted from persimmon fruit. This method typically employs a specific type of persimmon known as "shibu-gaki," which is high in tannin and not usually consumed as a fruit. The process begins with the harvesting of green, unripe persimmons before they ripen to orange. These persimmons are then crushed and pressed to extract the juice, which is stored and fermented for over a year to produce persimmon tannin, known as "kakishibu."

The history of kakishibuzome is ancient, with garments dyed using persimmon tannin, known as "kakiso," dating back over a thousand years.

One of the unique characteristics of items dyed with persimmon tannin is that their color deepens and transforms into a rich amber hue with use.

In modern times, kakishibuzome has regained attention as an environmentally friendly dyeing method that avoids the use of chemical substances.

Benefits of Kakishibuzome

• Strengthens materials: Provides robustness to the dyed items.
• Waterproof, preservative, and insect-repellent: Offers natural protection against water, decay, and insects.
• Enhances color over time: The color intensifies and develops into a richer hue with daily use.
• Environmentally friendly: Made from natural materials, making it a sustainable and eco-friendly dye.
