The front shape is the Wellington shape nearly close to square. The edges of the rim is softened so that the frame doesn't look too sharp. walpole's design was inspired by improving union's bridge part. This design was created by serendipity. Serendipity means the occurrence and development of events by chance in a happy or beneficial way. Serendipity is the word invented by Horace Walpole. We named this frame after his name.

Original titanium bridge
The pipe for a screw is normally soldered, but Walpole's pipe is the integrated bridge part which made of a piece of titanium. This idea is adopted to the end pieces. This original bridge enables the frame so durable.
