E-liquid bottles are containers used to hold liquid solutions designed for use in electronic cigarettes or vaporizers. These liquids, often referred to as e-liquids or vape juices, typically contain a mixture of propylene glycol, vegetable glycerin, flavorings, and sometimes nicotine. The bottles come in various sizes, usually ranging from 10ml to 120ml, and are often made of plastic or glass. Most e-liquid bottles feature a dropper or nozzle tip for easy filling of vape tanks or atomizers. Many also include child-resistant caps to enhance safety. Labels on the bottles provide important information, including ingredients, nicotine strength, and usage instructions.
