The .5ml dropper has no measurement indication marks.
A bit disappointed with the quality. Especially with how essential these are to have with your bottles. The top squeezy pieces wiggle within the cap that secures to the bottle. So opening can be a pain and they constantly feel like they will break. They aren't nice and tightly attached like they should be.
The dropper helps to conserve oils! That is a very economical aspect of this product.
