Precision Application Design: Features graduated measurement markings for accurate liquid dispensing, plus a tapered spout that delivers controlled, drip-free application - perfect for hair treatments, coloring, or craft projects requiring exact amounts. Leak-Proof Security: Each bottle includes a secure inner plug and outer cap that create a double-seal protection system. Won't leak even when tipped over, making them safe for travel or storage in your salon kit or bathroom. Premium PET Construction: Made from durable, transparent PET plastic that's lightweight yet sturdy. The crystal-clear design lets you easily monitor liquid levels while the material resists stains and odors from repeated use with various products. User-Friendly Features: Wide-mouth opening simplifies refilling, while the flexible bottle body allows for easy squeezing with one hand. The smooth surface wipes clean effortlessly after use with just water or mild cleaner. Multi-Purpose Versatility: Ideal for professional or home use with hair oils, serums, color treatments, as well as crafts (paints, glues), beauty products (nail art, henna), and even kitchen applications (oils, sauces).
