These empty lip balm tubes are made from lightweight plastic, each with a capacity of 5 grams. The set includes 100 black tubes and matching caps, designed for storing and dispensing homemade lip balms, lip glosses, or other cosmetic formulations. The container body is cylindrical with a twist-up mechanism at the base, allowing controlled product release. The black finish provides a neutral, professional appearance suitable for both personal use and small-scale production. Each tube measures approximately a standard lip balm size, making them convenient for pocket or purse storage. The plastic material is smooth and easy to clean before first use. These containers are intended for DIY cosmetic projects, enabling users to portion and package their own creations without branding or pre-filling. The caps fit securely to prevent leakage during transport or daily carry. Suitable for individuals who prepare their own skincare or makeup items at home, as well as for crafters, small business owners, or workshop participants. No product is pre-filled, so users must prepare their own formulations separately. The empty tubes offer flexibility in ingredient selection and can be reused after thorough cleaning. This bulk set helps reduce per-unit packaging costs while providing a consistent, uniform look for homemade products. The 5-gram size is adequate for trial batches or for travel-sized items. The plastic construction is lightweight yet durable enough for repeated use under normal conditions. Avoid exposure to extreme heat which may affect the tube integrity. These containers do not include any attached labels or branding elements, allowing full customization with stickers or direct printing if desired. The twist-up bottom mechanism operates manually and should be tested before filling to ensure smooth function.
