First of all, our storage room is maintained at constant temperature and humidity. Drastic rise and drop of temperature during day and night may cause the gown material to accumulate moisture in the air. Furthermore, our staff provides a regular check for your gown (every quarterly) and update you with the storage conditions. With tight securities (24 hours CCTV surveillance), your gown will be maintained at the optimum environment at all time. If yet, any yellow stains still develop during the storage period, we provide cleaning service free or else at a discounted rate.
