Actor Gu Hye-sun unveiled a handmade fountain pen following her hair rollers.
On the 18th, Gu Hye-sun posted several photos on her social media, saying "I made a handmade fountain pen."
The released photos show a fountain pen that looks as if pieces of leather have been joined together, catching attention.
Gu Hye-sun explained, "The price range is on the higher side, so I hope you view it as a work of art and also use it."
According to the accompanying sales L.I.N.C, the handmade fountain pen is 450,000 won.
Earlier, Gu Hye-sun developed hair rollers after developing the idea with researchers while enrolled in the master of engineering program at the KAIST Graduate School of Science Journalism last year.
However, the hair rollers initially sparked controversy for their high price at launch, but later recorded strong sales, leading her to transform into a businessperson.
