I am a complete dunk and dabber and not the least bit ashamed of it!
I absolutely love drowning myself in perfume and for the full size bottles I only get perfumes I like. After all, they are made to wear and use up and buy again! I am not worried about contaminating them because I am the only one who will ever use them and I go through them fast enough.
As for the leftover oil on my finger, after dabbing it on my skin, I just slide it in my hair for a longer, lingering scent! Then I wash my index finger with soap, water, dry it and voila. I am done!
So far I have not spilled any oils. Knock on wood, mirrors, glass, anything you want!
For imps I use the wand, unless I find out I love it and then dunk and dab again!
