Simple and precise chalk wheels. The black plastic applicator is filled with white marking powder that is applied to the fabric when the metal wheel is rolled. The resulting line is smooth, fine and easy to remove from your projects when you are finished. This method of applying chalk is handy and mess free.
Note that the opening for the metal wheel has been lightly waxed to prevent chalk from spilling in transit. To start your wheel rolling smoothly, run the wheel over fabric until the wax seal breaks.
