Twelve (12) vintage Majestic Buttons brand very dark navy blue (almost black) plastic buttons. You'll receive 9 buttons that measure 11/16" (18mm) and 3 that measure 9/16" (15mm). Measurements are corner to corner for square buttons. Rounded corner square with deep cup center and a notch running from side to side. The sides are gently curved and have a flat scooped area on about three-quarters of each side; this area is matte and has a very subtle striped texture. The backs have a thin flat and a raised flat pad in the center with a shallow channel in between. Two-hole sew-through. Three buttons are sewn to their original card with thread; the remaining buttons are loose. No care instructions but these should be washable. Made in Japan. Very good condition.
