We are currently unable to ship orders from WA State through April 9th due to a government-mandated shutdown for COVID-19. Orders shipping from Koolance Korea, manufacturing, and development are unaffected during this period.

We will continue to answer email. Backorders can still be placed through our website, which will be shipped once restrictions are lifted. (Payment is required for backorders later when they are being prepared.)
