- Ergonomic one-hand operation: press the handle to open the outlet and release to close the bottom opening, controlling dough flow and preventing drips. - Food-grade stainless steel construction: safe, durable and BPA free; corrosion and high temperature resistant; easy to clean. - Good sealing and drip protection: silicone seal around the outlet provides strong sealing; when closed, dough does not flow, helping keep hands and the kitchen clean. - Large capacity with convenient wide mouth design: top wide mouth makes filling easy and precise; 900 ml container stores the right amount of dough for efficient production and quick turnaround. - Practical use scenarios: 1) Filling batter into muffin, cupcake, or cake pans for consistent portions. 2) Dispensing brownie or cookie dough onto baking sheets in uniform sizes. 3) Piping or pouring batter into molds for layered cakes or specialty desserts with clean, controlled flow.
