Premium material: Made from high-quality PP (polypropylene) for durable, food-safe use. The rigid construction keeps the bottle shape and resists cracking under normal kitchen use. Precise mixing and portioning: Built-in measurement markings let you mix sauces and dressings to exact ratios so recipes turn out consistent every time. Ideal for combining oil, vinegar, herbs, and other ingredients directly in the bottle. Effortless one-handed use: The flip lever design opens with one hand — flip back to pour and flip forward to close. This makes pouring controlled and reduces drips and interruptions during food prep. Portable and practical: Designed as a portable salad dressing bottle for easy transport and use at home, picnics, office lunches, or outdoor cooking. Small enough to carry where you need fresh dressings or marinades. Versatile function and compatibility: Suitable for oils, vinaigrettes, sauces, and marinades. Use it to mix, measure, and pour a wide range of liquid condiments without switching containers. Use scenarios 1) Home salad prep: Mix a vinaigrette directly in the bottle using the measurement marks, then pour neatly over greens with a single hand while finishing other ingredients. 2) Grilling and marinating: Prepare a marinade by measuring oil and seasonings, shake to combine, and apply to meat or vegetables for even coverage. 3) Packed lunches and picnics: Bring freshly mixed dressing in the portable bottle to keep salads crisp and avoid soggy pre-dressed meals. What it solves Eliminates guesswork with clear measurement markings for repeatable results. Reduces spills and awkward handling with a one-handed flip-lever pour.
