Each of these empty tubes can hold approximately 10 mL (appx. 0.3 fl ounces) of lip gloss. The tubes have a durable, clear, shatter-resistant body with a gorgeous silver etched ring design below the shiny metallic cap. These are lightweight and great for traveling, gifts, or everyday use. Avoid overfilling: Wiper (stopper) inserts are designed to fall out if there is too much pressure in the tube. Stop filling about 0.5 inches from the silver ring to avoid overfills. Dimensions: -Length: 115mm (~4.5 in) -Width/Diameter: 15mm (~0.6 in) -Opening: 9mm (~0.35 in) Tips: -To Disinfect, use 70% isopropyl alcohol. Swish around and let the tubes air dry completely. -Wash the applicator brushes with mild soap and warm water, then let them dry before using to help soften and increase their absorbency. -If the little wiper/stopper falls out when filling, remove some product, clean the wiper and wand off, and retry.
