These sachets of Normasol Saline can be used for tattoo and piercing aftercare to gently cleanse the site. They contain a sterile sodium chloride solution that is the same concentration that is found in the body. These sachets are 25ml and are single use. Once they have been opened and removed any remaining solution should be discarded. These sachets are perfect for the travelling tattoo artists as you no longer have to carry about heavy bottles of saline. They also eliminate the risk of cross-contamination. The solution is isotonic so will not harm cells and is great for irrigating the skin once a tattoo is finished to wash away any excess ink. This solution is for external use only and should not be used orally or anywhere internally on the body.
