【Freshness Preservation + PSE Certification】The vacuum bags can be tightly sealed by removing air, blocking contamination from external moisture, microorganisms, mold, bacteria, dust, and other elements. This preserves the nutrients and color of food for a long time, effectively preventing spoilage and food waste. Not only does this keep your rice delicious, but it also protects your family's health! This vacuum sealer has PSE certification, so please rest assured. 【Multi-functional Vacuum Sealer & Cooker】① As a food preservation vacuum packer, it blocks air and bacteria from the outside, preserving the taste and moisture of ingredients like meat, fish, vegetables, fruits, and snacks, reducing spoilage and food waste, and making cooking and meal preparation easier. ② As a sealer, it's effective not only for storing food but also for storing photos, letters, precious metals, important documents, and everyday items. 【Improved Performance Compared to Previous Models】This upgraded version has improved performance in several areas compared to previous models. ① The appearance is the most lightweight and beautiful compared to previous models. ② Waterproof bottom. The bottom of the previous model was prone to water damage, which could destroy the machine. The upgraded version has increased exhaust ports instead of exhaust vents, making it difficult for water to enter and better protecting the main unit. ③ The upgraded version adopts constant temperature heating. It avoids the bag not being sealed due to the temperature being too high or too low, which could damage the food. 【Safe & Easy Operation + 15 Dedicated Vacuum Bag Rolls Included】Just press once, and you can vacuum seal or seal in seconds. The sealer has hook locks on both ends to prevent burns when the sealer is working. With an LED indicator light, you can check whether the work is completed with the indicator lamp. 15 dedicated vacuum bag rolls are included. This is a new, unused item that I received and stored without the opportunity to use it.
