Abstract: The present invention relates to a drug delivery device (6) comprising a dose button (1). Furthermore it relates to a method for manufacturing a dose button (1) by using a cutting-off process. The aim of the present invention is to minimize the risk of using a drug delivery device (6) containing a wrong drug. By means of tactile features, a drug delivery device (6) is distinguishable from another drug delivery device (6) containing another type of drug. This tactile feature is manufactured by using a dose button (1) out of metal which is milled or lathed.
