Kota reed diffusers are perfect for a space where you want to fragrance without lighting a candle, hallways, bathrooms, bedrooms...Ours come in a clear circular 100ml glass vessel with a gold cap in all our signature scents. Our "reeds" are actually a porous fibre and do not need to be flipped. They turn from dark grey to black once the oils have been aborbed, allow 2-3 days for scent to travel up the reeds. Our diffusers last for 2-3 months depending on room temperature. Available in all our signiture scents.
