Each item is handmade. Due to the natural materials used, there will be slight variations in color, shape, grain, and knots. The color of the actual product may differ slightly from the images. Also, during the charring process, small cracks may appear on the surface of the buttons, but a matte urethane coating has been applied, and we believe this will not affect their use.
