Natural shell buttons, approximately 13.5mm across and 1.5mm thick. As you can see, these range from glassy silvery-white to a more opaque brownish-black. If you have a preference as to colour, feel free to leave a note at check-out; otherwise, I'll pick a variety. The backs may also be somewhat uneven.
I take care to pick the best available buttons for each order but, since shell is a natural material, there may be slight imperfections and variations in colour. Please wash with care - avoid using acidic cleaners and tumble-drying.
