The thicknesses indicated here are in millimetres. For the conversion of Pirastro dimension (PM) applies:
1 PM are 0.05 mm.
Example: 0.65 mm are therefore 13 PM
Please note: We - and the manufacturer - make every effort to always supply fresh strings. This can lead to the fact that not all string gauges are always available at short notice. It would therefore be advisable to send us a short request (e.g. simply via the above link "Question about article") about the current delivery time of the desired string thickness.
