1.2-in-1 Dual Function: Seal & Cut in One Compact ToolCombines heat sealing and cutting into a single device—one end uses upgraded heating wire to create airtight seals for opened snack bags, while the other features a hidden safety blade for precise bag opening or trimming. Eliminates the need for separate clips, scissors, or sealers, simplifying food storage and package handling for chips, cookies, or 调料包. 2.Rechargeable & Long-Lasting: No Disposable Batteries NeededBuilt with a 3.7V 1300mAh lithium-polymer battery and USB-C charging port—charges via phone adapters or power banks, and lasts over a month on a single charge with daily use. More eco-friendly and cost-effective than battery-powered models, avoiding the hassle of frequent battery replacements. 3.Airtight Sealing to Keep Food Fresh LongerAdopts advanced heat-melt technology (no preheating required for upgraded versions) that creates leakproof, moisture-resistant seals in seconds. Tests show it seals chips bags tightly enough to prevent staleness and even holds water without leakage, extending food shelf life and reducing waste. Compatible with PP, PE, PVC, and laminated foil bags (up to 0.3mm thick) but not paper bags. 4.Portable & Space-Saving: Use Anywhere, Store EasilyWeighs only 45–80g and measures 3.5–5.5 inches long—small enough to fit in pockets, purses, or kitchen drawers. Perfect for home, picnics, camping, or travel. The built-in magnet lets it stick to refrigerators, and the optional lanyard enables wall hanging for quick access. 5.Safe & User-Friendly for All AgesFeatures a safety design with hidden heating wires (under a slide cover) and a recessed cutter to prevent accidental touches or scalds. A middle-position safety lock disables the device when not in use, making it safe for families with kids. The one-button operation and smooth sliding action require minimal effort—even seniors can use it effortlessly.
