Our refillable solid perfume compact contains 3ml of perfume. Just pop the tray into the magnetic base. Great to layer underneath our eau de toilette sprays as it will increase the longevity and wear time. When you're all done try a new scent or refill it again and again with your favorite fragrance. This is also a great storage piece to house your unused solid perfume trays when you're changing them out with our perfume lockets.
