Lot of two (2) used Chakoner heart-shaped refillable chalk wheels. Made in Japan. One for pink chalk, the other for yellow. Some amount of chalk is in each, but I'm not sure how much. Both are in working order, see the test photo on olive fabric for the line quality. These have heavy cosmetic wear to their plastic shell, there are innumerable scratches on both sides above the wheel part, probably from being run against an edge. See close-up photos. The plastic eraser brushes double as the stopper to the refill port. There is some flex wear to the bristles but they are all intact. Hard-to-find tool in the US, prized for its precision marking.
