Shin explained the usage while pointing at the writing paper and the message card. It was an item used often on birthday and Christmas in the game. There were people who made an elaborate card which induced a fancy special effect the moment it was opened.
The item was only used at certain times, because normally it was faster to email in the game, but it was certainly a convenient item, because in the first place, functions such as email and friend list were not usable in this world.
“Items as convenient like this exist too…”
“I do not use it too much and there are plenty left.”
The item was rarely used, even if he got many message cards and a lot of writing paper as quest and event rewards. Though they were not really useful in the ‘game’, the items were unexpectedly handy in ‘reality’.
“If this thing becomes popular, I think that would be amazing.”
“I guess so.”
