Four (4) vintage Lansing plastic buttons on their original card. They are slightly smaller than the 5/8" listed, closer to 9/16" and exactly 15mm. Chunky circle, about 3/16" (5mm) thick, with a white center that has a slightly textured surface. The rim is bright orange and appears to wrap around the white center to the back. The holes are set within tiny orange squares near the center of the top. The back is very slightly curved. Two hole, sew-through attached to cards with thread. Made in Japan. Very good condition.
