It's a snail mail! For those who didn't know snail mail, this is what Wikipedia says; Snail mail or smail (from snail + mail) is a dysphemistic retronym—named after the snail with its slow speed—used to refer to letters and missives carried by conventional postal delivery services. The phrase refers to the lag-time between dispatch of a letter and its receipt, versus the virtually instantaneous dispatch and delivery of its electronic equivalent, e-mail. It is also known, more neutrally, as paper mail, postal mail, land mail, or simply mail or post. An earlier term of the same type is surface mail, coined retrospectively after the development of airmail.
This was my first time to receive a snail mail from a foreigner friend :D So yeah, that's it! This is really unexpected. :)
