Polish Pen is water based, odorless, non-toxic, dries in under 40 seconds. Available in 5 Colors Red, Pink, Blue, Gold, & Silver. Our hoof polish pens apply a quick drying, non-toxic, coat of polish that is easy to remove. Only one layer application is necessary. On dark nails, we suggest doing a base coat of white first and then a color for a better result. Directions: Nail Polish must flow from pen nib for proper applications. FIRST USE: Shake pen well, remove cap, press nib of pen straight down on a protected surface until nib depresses slightly into body of the pen. Pen is ready for use when nib is all wet with polish (About a minute). SUBSEQUENT USE: Shake and depress nib to freshen with polish before use. TO REMOVE: Use a buffing block.
