Certainly, the Different Company (www.thedifferentcompany.com) has done justice to its name with its fragrance holders made of exotic leathers. The coverings in crocodile, ostrich, lizard, and other skins wrap snugly around the Paris firm’s rectangular, 250-milliliter bottles, which hold unisex scents that include Sel de Vetiver, Bois d’Iris, Osmanthus, and Jasmin de Nuit. Customization options include monograms, embossing, inset jewels, and caps in white gold, yellow gold, or silver. The holders start at $2,500. . . .
