You can follow the edge of a Leaves Galore or Hearts and More template with the chalk wheel to get a fine line to use for placement of appliqué or for quilting designs. Packaged with brush away chalk. To refill with Iron-Off Chalk Powder (sold separately), remove the clear plastic stopper on the top of the heart shaped tool, dump out the brush away chalk that it comes with, add Iron-Off Chalk Powder from the handy dispenser bottle. Now you have an iron erase tool. If you make a mistake, just iron it away. Why not have two! Keep one with brush away chalk and another with Iron-Off Chalk.
The color of the plastic case may vary.
