This "medium type" medical marker is hypoallergenic and gentle to the skin. The shape of the nib prevents lines from smudging and allows the user to draw firm, sharp lines on the skin. The use of a special water-based ink with good fusing properties ensures that the ink will not disappear easily. The color of the ink is violet. Marked lines can be erased with commercially available isopropyl alcohol (IPA). Each packet is labeled with a serial number and expiration date for convenient management. The sterilization cannot be re-established. Please observe the expiration date indicated on the package. The ink contains no metal and does not generate dioxin when incinerated.
