Well I bought one of these for US$50 roundtrip first class.
Has someone here used it???

It has no booklet explaining it, its supposed to be valid from any Border city to Prague and from Prague to any border city.

But I don’t know how to validate it or if I can just take an ICE from Berlin to Prague just having the two passes (Eurail and PEP).

According to the instructions on the Eurail pass booklet, the only case you can use your Eurail pass without validation is when you are traveling for the first time from a non Eurail country to an Eurail country so you can have your pass validated by the conductor. So I think this could also apply to this pass, but I’m not sure.

Any suggestions??
