Lois Hong and Xiaoxiao are two Chinese girls who share a love for mountains and art. They met while climbing Manaslu — Xiao liked drawing peaks with colourful pens, and Hong loved capturing peaks through her lens. In 2025, Hong invited Xiao to draw 14 rainbow peaks for Out of Skool. And just like that, the 14-Peak Rainbow Mug Series came to life - full of colours, stories, and mountain loves.
