Use these to fill my small car diffuser bottles.
Syringe - 10ml.
I use this to accurately measure small amounts of glycerin or vitamin E to add to my moisturiser for nightly or daily use, for face and neck.
I also use this to measure my mouth wash after brushing my teeth as well.
Though this is a one-time use only, I re-use it by washing it in warm water and dishwashing detergent, and air-drying it. I highly recommend.
This syringe fits into the pump bottle and therefore is ideal for measuring out the 5% required (to be added to the face serum).
