Ik ontving volgend bericht van een italiaanse delcamper.

Here you have the answer that regards all the phonecards from Italy you offer. Are they still magnetic? Probably you know that the italian cards have some value only if the black strip is still magnetic. To check for it you can use some iron filing and see if some of them remain on the strip. If yes the card is magnetic otherwise it has no value (or very low value). Of course you have to be careful when removing the filings to not scratch the cards.
So could you tell me if the cards are magnetic?

Wie weet mij daar iets meer over te vertellen ? Ik heb de proef gedaan en al mijn telefoonkaarten van Italie zijn niet meer magnetisch.
Bedankt,Daadze
