These plastic bottles are ideal to keep in your tattoo studio as you cannot always know when they may need one. If you regularly mix your own shades of ink, this can be a superb supply to have in the workspace as you can easily store your new shades and tones. Keeping them free from contaminates is also vital, which can be tricky if the ink is kept in small ink caps that do not have proper secure lids or caps. These bottles are supplied with protective nozzle caps with help to keep the ink sterile and hygienic for use. They also help to ensure that the ink is protected from contaminates such as bacteria, germs, infection along with general dirt and grime.
