This is a tabletop heat sealer. It's a set including the outer box, the main unit, and two replacement parts for the heat sealing area. I used it to seal about 130 plastic bags for making wedding favors. The temperature can be adjusted in 8 stages with a knob. I used it to seal plastic food packaging bags, and setting it to level 4 was just right. The outer box and the styrofoam cushioning inside have tears and damage as shown in the attached photos, but the main unit is in good condition. Please refrain from purchasing if you are concerned about it being stored at home. #sealer #tabletopsealer #heatseal #heatsealer #petitegifts
