I was given a leather long wallet as a birthday present.
Compound of 長い (long) + 財布 (wallet). Traditionally seen as a more formal or businesslike choice than a folding wallet because it keeps bills uncreased.
Pronunciation
Usually ながざいふ, with the voiced ざ of compounds such as 折り畳み財布; the unvoiced ながさいふ is also heard.
