Safequistle was established in 2009 to prevent damage to people and assets caused by gas fires in houses. It is a company that is improving vertically after continuous development. Quisels Smart Gascock, which is produced by the company, has the highest quality among products of its kind in Korea, and has been certified as a venture company in 2011 and as an innovative small business in 2013. In order to be reborn as a gas appliance business, we hope to increase our vertical sales by targeting gaps in the market and focusing on listing the KOSDAQ.
