A beautiful addition to your home or office, these jars can be used as pen holders, planters, or candle vessels. Each 15 oz cement jar is handmade in Georgia and sealed with a non-toxic sealer. Vessels are reusable even if candles have been poured in them. Just wash with mild soap and warm water to repurpose. Since each jar is hand mixed and poured, each one will be unique and some may contain imperfections. Air bubble and slight color differences are to be expected.
