I have never found toner and astringent bottles user-friendly. More often than not I spill too much onto my cotton pad. The Clinique bottle is most guilty of this.
Then I found this.
Quo has these great travel side containers that come with pre-printed labels. I simply pour my toner of choice into this bottle and tighten. Now a few sprays onto my cotton pad and I’m getting more of what I paid for.
