LocknLock Bisfree Press fermentation container

LocknLock is a globally recognized brand specializing in high-quality kitchenware and home storage solutions. Originally founded in 1978 in South Korea, the brand became a household name following its invention of the innovative four-side locking airtight container system in 1998. This specific product line, the Bisfree Press, is designed specifically for traditional fermentation processes such as pickling and kimchi making, featuring a specialized inner press plate to keep food submerged.

Over the decades, LocknLock has expanded its manufacturing footprint significantly beyond South Korea, operating major production facilities in Vietnam and China to meet global demand. In 2017, the company underwent a major ownership shift when the founder sold the controlling stake to a global private equity firm. Today, the brand continues to lead the market in safe, BPA-free plastic and glass storage technology, maintaining its headquarters in Seoul while distributing products to over 100 countries worldwide.
