A 15ml or 1/2 oz cobalt blue glass bottle fitted with slow dripulator cap filled with our Impress Purple Lavender Essential Oil, we steam-distill this from our own flowers in our award winning distillery. This is the one you want for making up soap, laundry product and for aromatherapy/room scent. I use this in my own eco-friendly home cleaning regime, I use it for mild burns and first aid and I love what our regular customers say about its quality and scent.
