A Zahir is an object (any object) that creates addiction. It was contrived by the Argentine author Jorge Luis Borges in 1949. In his short story, also named "El Zahir", the Zahir was a ten-centavo coin with the letters "N","T" and the number "2" scratched into it. This is a phone receiver. Looks like someone really wanted to have it. Do you want to have it? I heard there's someone roaming the streets of Delpher, collecting every last phone receiver out there.
