I purchased this, but the size wasn't suitable for my medication, so it's unopened and unused. Made with food-grade polypropylene, it's BPA-free, non-toxic, and environmentally friendly. Diameter 9cm * Height 2.5cm (when closed), weight: 30g. It doesn't take up much space, making it portable. It easily fits in bags and pockets. It has good sealing properties, preventing medication and supplements from oxidizing. Compact size for storing essential medications, convenient for carrying to work or school, travel, and business trips. Convenient for storing essential medications and supplements compactly, and carrying them to work or school, travel, and business trips. The rounded design makes it easy to carry in pockets or bags. There's no need to worry about it scratching other belongings.
