Hidden Glo Disappearing Tailors Chalk
36 pieces per box
The chemicals formulated in this chalk are similar to those used in Perfection Master Disappearing Chalk "Slo Formula". The difference is that this product contains a special florescent compound which will remain in the fabric after the visible mark has disappeared. The fluorescent mark will show up under "black light" even though the naked eye can observe no markings.
Recommended use: Where marking will be available for use even after the disappearance of visible marking occurs.
