Whether on a shelf or as a centre piece for a coffee table or placed wherever your heart desires you will enjoy them as much as I did creating them. All shells come sealed in a light gloss finish. For cleaning, they should be gently wiped with wet cloth but not submerged in water as they are not fully waterproof. A gorgeous gift for any occasion (Wedding, Birthdays, Bridesmaids, Christmas, etc) and come in a variety of designs. Each shell is unique resulting in a truly one of a kind design for you.
