If it's not labeled with your name, your coffee mug legally can be used by any person, animal with opposable thumbs, or sentient plant that wants to drink from it. Stake a claim to what's yours with today's Groupon: for $40, you get a custom-made fragrance at Essence Fragrance Lab, located on Newbury Street (up to a $100 value).

Essence Fragrance Lab tickles discerning noses with its fragrances and blendable scents. A custom scent can be created with more than 300 perfume oils, including carnation, blue lilac, cedarwood, coconut, and more. Once base notes, middle notes, middle base notes, upper middle notes, and top notes are selected, the head perfumer concocts each creator's body bouquet on-site for immediate neck dabbing. Each oil is alcohol-free, perfect for sensitive skin, allergies, and adding to tiramisu intended to be sold at a children's bake sale.
