A candle in a teacup is a charmingly unique decoration. It is usually made of a scented wax, typically a soothing and calming scent like lavender or jasmine. It is small enough to fit snugly into a teacup, and when lit, gives off a gentle, flickering light that casts a warm, inviting atmosphere throughout the room. The candle's aroma is gentle but fragrant, filling the air with a relaxing and calming scent that is both comforting and inviting.
