Jacquard stainless steel tips, when combined with our softest-available half-ounce bottles, are the easiest tool to master when first learning henna. With a variety of tip sizes, you can gain different effects simply by switching the tip. These tips, in .5, .7, and .9 mm in diameter, hold up to rigorous use and are easy to clean with warm water and soap. Simply screw onto the jacquard bottle plug to use. Wash thoroughly with warm water after use. Not compatible with Luer bottles.
