Refillable Perfume Atomizer 5ml Perfume Bottle, Boriyuan Mini Travel Empty Portable Perfume Spray Bottle (Black + Gray)

These are so easy to use. One of my cologne bottles, after I removed the diffuser from the atomiser on the cologne bottle, had to wide of an opening to be able to be used with these decants but with my other fragrances they worked well. The problem was that once I removed the diffuser (top portion that sprays out the cologne) the stem had a flange, that made it too wide to fit into the bottom of the refillable portion of the decant. The amount of fragrance that you can have at your disposal is perfect for about 3-4 days. I use this to be able to just reapply in the afternoon after about 5-6 hours at work. Also being careful to be sure I haven't become "nose-blind" (reapply too much) so these are great just for a quick sprits. Portability: container fits great in a trouser pocket. The way that the decanter works makes sure it is locked and no spillage occurs. I will definitely be purchasing more for other fragrances. I like to buy and try EDT fragrance clones (more cost effective), so some of these are not as long lasting as an EDP, that's where these atomisers are perfect.
