These empty lip balm tubes are designed for DIY cosmetic projects and personal use. Each tube holds 5.5 ml (0.18 oz) of product, making them suitable for homemade lip balms, lipsticks, or glosses. The containers are made from BPA-free plastic, which helps reduce exposure to certain chemicals during use and storage. The twist-up mechanism allows for easy application and retraction, while the color caps add a simple visual identifier. A leak-proof design minimizes the risk of mess during filling or daily carry. The set includes 50 pieces with green caps, offering a practical quantity for batch making or sharing. These containers are intended for use with oil-based or wax-based formulations typical of homemade balms and sticks. The smooth interior walls allow for even filling, and the twist mechanism operates without sticking when properly filled. Suitable for individuals who create their own lip care products at home or for small-scale gifting. The tubes are not pre-filled and require manual filling and cooling before use. Their compact size fits easily into pockets or small bags. The material resists typical wear from repeated twisting and moderate handling. Cleaning before first use is recommended to remove any dust from manufacturing. These tubes are not designed for high-temperature applications or for use with water-based liquids. The BPA-free claim refers to the absence of bisphenol A in the plastic composition, in line with common safety standards for cosmetic containers. The pricing per tube is economical due to the bulk packaging, making them a cost-effective option for routine DIY projects.
