The 15ml size represents a compact volume measurement commonly used in liquids, particularly in industries like pharmaceuticals and cosmetics. This size often accompanies sample sizes, travel-sized products, or precise dosages, providing convenience and portability. In skincare and cosmetics, 15ml containers commonly hold serums, eye creams, or spot treatments, offering enough for trial purposes or on-the-go usage. Similarly, in pharmaceuticals, this size is used for medication samples or smaller quantities needed for short-term treatments. Its compactness makes it ideal for those prioritizing convenience or needing to adhere to airline travel regulations on liquid quantities. Additionally, manufacturers favor the 15ml size for its cost-effectiveness in production and distribution, meeting various consumer needs while reducing waste. Whether for personal care, medical use, or scientific experimentation, the 15ml presents a practical solution for containing liquids economically and efficiently
