Best Friends Creations takes granite scraps and repurposes them into elegant oil lamps. The granite is drilled and then equipped with oil reservoirs that we make from recycled glass products. Each lamp is equipped with a glass wick assemblies and fiberglass wicking so you never have to replace the wicks. Reservoirs are affixed and sealed with oil resistant sealant. We provide instructions and a funnel for easy refilling. Attractive for any room in your home. Depending on the size of the reservoir, when lit rock will generally burn 2-3 hours before having to refill. AS ALWAYS... never leave a burning rock or candle unattended and keep away from children.
