How about getting your friend a personalized perfume bottle that no one else has? Many companies now offer custom fragrance services where your friend can create their own signature scent and have it presented in a unique, one-of-a-kind bottle. Alternatively, you can also find many vintage or rare perfume bottles on websites such as Etsy or eBay. These bottles can be a special addition to their collection and may hold sentimental value as they may no longer be in production.
