Microbiome cosmetics brand YUIK will release its "Biome Barrier Melting Moisture Lip Balm" collaboration with its brand models RIIZE on its official online store on the 23rd. The collaboration combines YUIK's lip balm with RIIZE's official characters "Little RIIZE," pairing each balm with a dedicated silicone case. Featuring all six characters — Rizeko, Songyongdori, Uraakbam, Tonyangduck, Ttolbyeong and Meongryongi — it comes in two colors, Original and Rosy, in options ranging from single items to three-piece sets and a six-piece special set. Buyers will receive a brochure with a RIIZE group photo. Those who buy an Original or Rosy three-piece set get a set of postcards, and buyers of the six-piece set featuring all characters receive a set of photocards with the members' handwritten messages.
