What LOCK&LOCK does
LOCK&LOCK is a Korean-founded global household goods manufacturer established in 1978 and headquartered in Seoul, with a 501-1,000 employee base. The company pioneered the world's first four-sided locking airtight container in 1998, which remains its signature technology and category-defining IP, and has since built a diversified portfolio across four primary categories: food storage containers (Classic, Bisfree Modular Plus, All-Tritan, The Clear, The Cube, Freezer Fit, Fresh Maestro Vacuum, Barohanggi), beverageware (Metro, Blissoul, Beer Tumbler), cookware (Decore IH, Hard&Light, Balance Cook IH, Soma, Salon cast iron), and small kitchen appliances (Steam Air Fryer, Portable Blender, hygiene sanitizers). Proprietary technology platforms include the four-sided locking system, HardLock surface hardening, Fresh Maestro vacuum sealing, Mediguard biocompatible materials, ceramic coatings (ART EGIS), and a Smart Modular stacking architecture, with materials expertise spanning Tritan, polypropylene, heat-resistant glass, stainless steel, and cast iron.
The business operates through eight wholly-owned overseas subsidiaries in China, Vietnam, USA, Germany, Thailand, Indonesia, and India (established 2025), with Vietnam functioning as the global production hub featuring plants for plastics, heat-resistant glass, and cookware. Distribution reaches 120+ countries via a multi-channel architecture: company-operated e-commerce platforms (locknlockmall.com, regional sites), 40+ direct retail stores in Vietnam and additional stores in Thailand and Indonesia, and B2B2C partnerships with major retailers and marketplaces including Target, Macy's, Costco, QVC, Amazon, Parkson, Vincom, Shopee, Lazada, Tiki, and Alibaba. The company also operates premium sub-brands (Daekket for cuisineware, Blissoul for lifestyle beverageware) and is extending into character IP via a January 2026 MOU with KOCCA.
Revenue is generated primarily through one-time hardware product sales to end consumers via diversified retail and e-commerce channels, with no disclosed subscription or recurring revenue component. The company is privately held (legal entity LocknLock Co., Ltd.) with no external investment, M&A activity, or parent company disclosed, and is led by CEO Lee Young-sang and Representative Director Kim Sang-young. Brand strength is evidenced by 23 consecutive years as Korea's #1 airtight container brand (K-BPI), 14 consecutive years in Vietnam's Top 10 Most Trusted Brands, and a sweep of the 2024-2025 iF, Red Dot, and IDEA design awards.
