No special care is needed: preserved roses do not require watering or direct sunlight and are sold as no-care displays intended for indoor placement.
Typical contents listed are one preserved flower box, a user manual, and a decorative ribbon.
The preserved roses are described as remaining fresh and colorful for up to three years.
Pendants are described with polished or diamond-cut finishes and made from solid 14K two-tone gold (one listing also mentions a white-rhodium finish). Care guidance listed is to wipe the piece with a polishing cloth.
