This 15 ml Winchester bottle made of amber glass comes with a dropper. It also has UV filtration from the amber glass.
Use this bottle to have a glass dropper and to have a small one for on-the-go. This works great, for the KITS, CDS at the end of the bottle and all WPS. The rubber seal may only last for a short time with WPS products, so it is more suited for short-term use, like travelling.
