Cave Candles are trade marked and totally unique to Natural Creations. They all vary in size and shape with average measurements for these medium sized Cave Candles being 5" to 7" tall and 4" to 6" at the base. These really cool rock candles can go inside or outside and they are all rubber bumpered on the bottom to help protect your furniture. Cave Candles are great for indoor or outdoor use. They are very weather resistant because the are all hand crafted from Featherock (pumice). Since the candles are shielded on three sides, this also helps to block out the wind on a breezy day. So whether it is day or night, on your deck or on your desk, our Cave Candles are very visible. What a great conversation piece. Your friends will not stop talking about them. Each one comes with 2 tea lights. Delivery time is just 1-2 weeks.
