How does dye coloring described in leather specifications differ from pigment coloring?

When reading in leather product descriptions that dye is used instead of pigment, one might wonder how the two processing methods make a difference in appearance or the feel of use.

hmmm editorial answer

While pigment covers the leather surface with a layer of color, dye permeates deep into the leather fibers, leaving the original grain completely intact.

This is a cotton-cover notepad processed with a tent fabric press machine to preserve the texture of cotton and finished with a light water-repellent treatment. Inside, it contains 68 pages of original pingraph paper printed with blue 1mm grid lines on unbleached pulp. It is a dedicated refill designed to be combined with a snap pad and used across two split left-and-right pages.

Why this product

From the grain of the paper to the touch of the cover, this item is tailored and refined for recording.

  1. Unbleached inner paper with blue grid

    It uses POSTALCO original inner paper printed with 1mm blue grid lines on eco-friendly unbleached pulp paper.

  2. Pressed cotton cover with water-repellent finish

    The original texture of the fabric is preserved by applying a light water-repellent treatment to cotton pressed with a machine for tent fabrics.

  3. Dedicated configuration divided into 2 left and right sides

    It is a dedicated product meant to be inserted into a snap pad, consisting of 17 sheets and 68 pages divided into 2 left and right sides.

Blue 1 mm grid lines are printed on pin-graph paper made from unbleached pulp, and PFAS-free pressed cotton is used for the cover. It features a structure divided into two pages on the left and right, and the surface has undergone a light water-repellent treatment. It is used to record thoughts by attaching it to a snap pad and combining it with other refills.

Why this product

Chosen for its eye-friendly grid paper, water-repellent cover, and freely combinable standard size.

  1. Unbleached grid paper construction

    It uses POSTALCO's original pin-graph paper made from unbleached pulp. Blue 1 mm grid lines are printed on the paper.

  2. Water-repellent treated pressed cotton cover

    The cover is made of pressed cotton material free of PFAS ingredients. Instead of waterproofing, it is coated with a light water-repellent treatment so it can be handled comfortably in daily life.

  3. Snap pad custom size

    It is a dedicated refill pad sized to fit properly into a snap pad. It has a structure divided into two pages on the left and right, and can be organized and used as desired by combining it with other refills.

Filled with unbleached pulp inner pages featuring a blue one-millimeter grid inside a cotton cover processed with a tent fabric machine and treated with water repellency. With its ring binding method, it lies completely flat on a desk without lifting, and folding the cover back stably supports your palm. Measuring width 14.8 cm by height 21 cm, it is well suited for keeping various everyday records.

Why this product

Because it was made with delicate consideration for every spot where hands and paper meet while writing.

  1. Original pin-graph interior paper

    Applied a blue one-millimeter grid on paper made of unbleached pulp. It is great for neatly filling in writing or drawings along the dense grid lines.

  2. Binding designed for opening and supporting

    With the ring binding method produced since 2004, it opens completely flat on a desk. It is designed so that when the cover is turned back, it extends below to support your palm.

  3. Water-repellent pressed cotton cover

    Cotton pressed with a machine for making tent fabric is attached to the cover. Light water-repellent treatment is added to prevent moisture and dirt in daily life.

A cotton cover compressed with a tent fabric machine and unbleached pulp grid paper are bound with rings. Because the rings are situated on the inside, it lies flat on a desk, and a label can be attached to the spine.

Why this product

Chosen for its binding that lies flat against the surface and its detailed grid inner pages.

  1. Unbleached grid inner pages

    Blue grid lines spaced 1mm apart are printed on paper made from unbleached pulp. You can write text or draw tables in detail aligned with the reference lines.

  2. Ring binding that opens flat

    By placing the rings on the inside, it opens completely flat on a desk. Even when stored on a bookshelf, it is convenient to distinguish contents by attaching a label to the spine.

  3. Compressed cotton cover

    A cotton fabric pressed with a machine for tent fabric wraps the cover. A fabric containing no PFAS components is used.

Why does the Three Pen Case use different leathers for the exterior and interior?

Seeing that a single small pencil case incorporates as many as three types of leather, one might wonder how each part is divided.

スリーペンケース
hmmm editorial answer

The Three Pen Case uses different leathers divided across three areas—the exterior, the interior, and the lining—tailored to where hands and pens make contact.
