Unfortunately I cannot recommend.
Unless the box I received was faulty ( as in no detectable oil in any of the "100%" oils ), there is no oil in any of the bottles I received. There is no smell in any of the 6 bottles.
If the seller feels this is a mistake then I will re review and update my findings.
At present a total waste of money.
