There is no danger of the test liquid dripping or transferring onto other objects on your workstation or your clothes and skin. The hawo InkTest PRO and InkTest HDPE comes in packaging designed especially for ease of use (30 x) with the aluminium packaging ensuring that the ink is protected from sunlight.
