Brand new, unused item! A convenient item that speeds up the thawing of meat and fish!! This thawing plate is made of aluminum alloy and can thaw food in about 10-12 minutes. I accidentally bought the same product twice, so I'm selling this one. m(_ _)m - Product Name: PASSO Thawing Plate - Size: M size - Approval: Approved by the Ministry of Health, Labour and Welfare - Thawing Time: Approximately 10-12 minutes (about 5 times faster than natural thawing) - Material: Aluminum alloy Thank you for looking.
