The special registration envelope and stamp illustrated here are used to mail currency and valuables within Korea only. The white envelope, 5″ x 9″ has an inner envelope made of paper of the same type used to cover doors and windows. Money, bonds, jewelry, and other valuables can be mailed in this. Money is not to be sent even by the usual registering of letters in Korea which costs 100 Hwan and is only to assure receipt of a written letter and is done without a value consideration.
The envelope is reversed in our usual sense of an envelope. On the side we would consider the front, there are three areas of Korean Hangul writing. (Editor 2020: see figures 4 and 5 for best examples of what Lyman Hale meant.) At the bottom is written “published by the Bureau of Communications“. The group of three characters along the right hand upper edge of the envelope means “sender“. At the left side in red is “Warning 1. This envelope is for the use of currency and valuables. 2. Seal completely.“
