I was bored one day, and decided to take on a "quickie" DIY. I pulled out scent reservoir.
I used a standard, slotted screwdriver, and popped off the top that holds the wick in place.
I decided to use some of this Victoria's Secret "Hazelnut Truffle" body mist that I hadn't used.
I got it for $2. It was on a 50% off sale at a thrift store.
I filled it up, and reattached the cap.
I plugged it in, and enjoyed. Took me about 5 - 10 minutes.
