* Buffalo buttons have individual differences due to the structure of the material, and even within the same lot, the color, pattern, and glossiness will differ. Please understand that it is a unique characteristic of the real thing. * Buffalo buttons are a material that is sensitive to heat and water. Do not hot press, tunbler dry, wash with water, etc., as oil and fat will be lost, causing glossiness, cracking, cloudiness, deformation, etc. * When cleaning, remove it from the product or protect the buffalo and use petroleum-based dry. * When processing the product after sewing, be sure to attach the button later. * Although the color is fixed after dyeing, the effect may be low depending on the quality of the buffalo, so please perform a thorough test before starting production. Also, avoid using a color scheme as there is a risk of discoloration and dye transfer.
