WHAT OUR CUSTOMERS ARE SAYING
As always, 39 Degrees hits it out of the park with their bath blends. This is my first time trying their new Ritual blends, but I'm already in love! So soothing after a long day and they all smell divine - you can tell love and care have been poured into each bottle.
Absolutely love the Hammam bath tonic. The scent is perfect and is not overpowering. So calming , Helps me to slow down and I feel centred, grounded and relaxed. It has helped me with stress and tension relief and reduce anxiety. I highly recommend.
Sit back & relax in the lovely scent
I got this one because I was intrigued by the cinnamon. I love the subtle scents of all the bath tonics so far. I don’t enjoy strong florals or musk scents so am very fussy with what I will use. This is delicate delicious and delightful! Love it!
All great tonics i have a different favourite depending on how im feeling great supporting a small business go girls xx
