The slim, cylindrical shape is great for organizing small items, especially when traveling.
Small Parts: Use it to store things like hair pins, bobby pins, small earrings, or needles.
Travel Kit: It can hold a small amount of solid glue, a tiny amount of toothpaste tablets (for short trips), or even be used as a mini-vase for a single delicate flower.
Making your own products is almost always cheaper than buying them pre-made. By reusing the container, you eliminate the need to buy new pots, jars, or applicators for your DIY creations.
