My favorite one lol

Still but strong power: The 'moon jar' that BTS RM fell in love with

"The image of the moon jar standing under the lighting in the gallery where external light is blocked is calm. As time passes from day to night, the moon jar shines more and more"

"It like watching a creature quietly but strongly proving its 'existence'. I think I know what the meaning of 'the vitality of white porcelain' Kwon Dae-seop talks about. According to Kwon's words, white porcelain is the best and strongest display of the vitality of the soil"

A modern interpretation of Joseon white porcelain was displayed by Ceramic artist Kwon Dae-seop's in Busan

BTS's RM also purchased a moon jar. He personally visited the studio to meet the artist "I came after studying about your works and white porcelain" https://n.news.naver.com/article/082/0001064378
