At Paypal, I was forced to return the payment to the buyer who voluntarily chose to send in a regular letter at his own risk. Unfortunately, for this reason, I was forced to cancel the normal mailing option. Please do not request this option.
I send everything exclusively by registered letter !!

Bei Paypal musste ich die Zahlung an den Käufer zurücksenden, der sich freiwillig entschied, auf eigenes Risiko einen regulären Brief einzusenden. Leider war ich aus diesem Grund gezwungen, die normale Postversandoption abzubrechen. Bitte fordern Sie diese Option nicht an.
Ich sende alles ausschließlich per Einschreiben !!
