[Dyeable Materials]

• Cotton, Linen

• Blends of natural fibers and synthetic fibers (50% or less synthetic content)
  If even 1% synthetic fiber is included, the original color may remain after dyeing, resulting in a mixed shade of black and the original color. Uneven color may also appear in some areas.

• Garments with unknown fabric composition
  Dyeing can be done with the understanding that the garment may not turn fully black.

[Non-Dyeable Materials]

• Silk, Rayon, Cupro, Tencel, Lyocell
  We cannot accept garments that contain silk due to the nature of the fabric.

• Wool, Cashmere, Mohair
  We cannot accept garments that contain those materials due to the nature of the fabric.

• Garments with more than 50% synthetic fibers
  Includes polyester, polyurethane, acrylic, nylon, and similar materials.

• Fur, shoes, neckties, and down (padded) items
  Not accepted.

• Leather items
  May shrink or harden, causing damage. Items with non-removable leather parts (such as bags or caps) are not accepted. If some leather parts are removable, please contact us in advance.

• Acetate, Triacetate
  These materials shrink drastically and become unwearable. Even if only 1% is present, we cannot accept the item for dyeing.

[Accessories]

Buttons may discolor, crack, or occasionally break during dyeing. If you are concerned, we recommend choosing the optional button removal and reattachment service.

Non-removable tack buttons, fly buttons, and metal parts may become scratched, discolored, or break in rare cases.

Patches, beads, or glued decorations may peel off.

Sewing thread, embroidery thread, and buttonhole stitching often use polyester, which does not absorb dye. For example, white polyester thread will remain visible against the newly dyed black fabric.

Metallic threads (gold/silver) may break or discolor during the process.

Vintage garments or those with fading or wear may not dye evenly. Areas with heavy wear may remain lighter or even tear during the process.

Distressed garments or those with raw hems may become more frayed or damaged. In extreme cases, they may no longer be wearable.

Garments with special finishes (e.g., water-repellent, oiled, wrinkle-resistant) may not take dye well or may not dye black at all.

Stiff or canvas fabrics may retain deep creases or develop white scuffing on the folds. They are harder to dye evenly and may show patchiness.

Residue such as invisible oils, stains, or particles may prevent dye from adhering evenly.

Garments labeled “dry clean only” may shrink. We can’t dye wool, cashmere or mohair contained garments.

Items with linings, shoulder pads, or internal structures are highly likely to lose their shape and may not be wearable after dyeing. Please contact us in advance if you are unsure.
