Leather color and printing can refer to the leather sample color reference product page in the store: https://www.pinkoi.com/product/szbXUTTC Please note before placing an order: 1. Leather is a natural product. In order to preserve the most natural state of leather, we insist on not covering it with heavy chemical paint. Surface scars, growth lines and plaques are natural lines. 2. Leather is a water-dyed product, and the color of each batch of leather must have a drop, whichever is the actual product. 3. The color of the leather will be somewhat color-shifted for each computer monitor, whichever is the actual color. 4. The characteristics of vegetable tanned leather are more likely to be scratched. If it is accidentally scratched, the leather will gradually become deeper with the daily use, and the traces will gradually become less obvious. The traces of the years of use will become your unique and exclusive leather goods. 5. For routine maintenance, please use a dry cloth or brush to remove dust, then use leather to maintain the oil and lightly apply the leather surface. 6. Store in a cool, ventilated place for daily storage to avoid mildew or excessive moisture. 7. Do not touch the water with leather. When the leather piece accidentally touches the water, please dry it immediately and let it dry in a cool place. 9. Since the typing service is purely hand-made, it is not using machine embossing, so it is impossible to achieve zero-error calibration. Please forgive me. 10. If you are unable to accept the above, please do not place an order.
