I have been using the whole bundle of KOH for 3 years now and their service is impeccable and any small problems are rectified with no questions asked.
I have introduced my children/grandchildren to KOH. Plus friends.And bought the bundle for them as a gift.
They told me it’s the best present they could have.
I thought as I promote KOH and buy it a nice little gesture would be appreciated. Even if it’s just the atomisers as I have a large house and like 1 in each area
