A refillable glass oil pillar candle is a simple, lovely-looking way to cast a warm glow, and it runs on a paraffin oil alternative. It’s made with durable, hand-blown borosilicate glass and can work indoors or outside. Pick from three pillar sizes that each come with a funnel, or go for the trio, funnel, and fuel set with Firefly Fuel’s own lamp oil that is long-lasting and cleaner-burning. Smoke- and soot-free and odorless. Oil is Made in the USA.
