This button features four linear holes that resemble a sashiko stitch. It comes in two main materials - bamboo wood and acrylic.
The acrylic collection includes the following colours: "Smoke" with a white swirly pattern, "Nebula" with a marble-like pattern that resembles the interstellar clouds, and "Candy", which features a range of bright and cheerful colours. There is also a degree of transparency to the acrylic buttons, which allow the fabric colour underneath to show through.
Please note that due to the randomness of patterns on the acrylic buttons, each button is slightly different in appearance.
