5L Stainless Steel Soup Warmer, KIPROSTAR PRO-KSW5 Model. - Brand: KIPROSTAR - Model Name: PRO-KSW5 - Capacity: 5L - Material: Stainless Steel - Type: Soup Warmer Thank you for looking. This is a non-electric soup warmer that uses a bain-marie or paste-type heat source. I purchased it about 7 years ago and used it a few times at market stalls to hold soup. It's useful at markets and the like because it doesn't require electricity. Please check the photos for the condition, as all parts and the instruction manual are included. There are signs of use on the exterior, but no functional defects. Please refrain from purchasing if you are sensitive about condition.
