Carefully Selected Genuine Materials with Environmental Consideration
“I want you to use it for a long time.”
From this sentiment, we were meticulous in our choice of materials.
We adopted top-grain premium leather tanned with plant tannins.
This original leather from BLUE SINCERE conforms to your hand from the start, with a soft and smooth texture that is appealing.
Unlike sheep leather or synthetic leather, it is not easily scratched, and by using cow leather sourced from Bangladesh, it is also environmentally friendly and can be used for a long time.
Simple and Slim Design
It has a compact size that fits neatly in your bag.
While being practical enough to securely store necessary pens, its slim design does not take up much space.
It combines a lightness that makes you want to carry it every day with a quality that shines in business settings.
Golden Ratio Design Combining Slimness and Capacity
The L-shaped zipper opens wide, making it easy to see the contents and smooth to access.
Despite its slimness, it can neatly hold necessary stationery, providing comfort in being able to quickly retrieve what you want.
The beautifully streamlined form is perfect for adult women.
It blends naturally in both work and private settings and is highly appreciated as an elegant gift.
Care Instructions
・It is not completely waterproof, so please be careful of water exposure.
・Moisture can cause stains, color fading, and changes in texture. If it gets wet, immediately wipe it lightly with a dry cloth and dry it in the shade.
・Avoid storing in direct sunlight or in high-temperature and high-humidity places.
・Please refrain from using alcohol-based solvents such as benzene or thinner, and do not wash it with water.
