Firefly 16 oz Refill Bottle Wide Mouth Applicator

Easy-Refill Oil Lamp Bottle

The Firefly 16 oz wide-mouth bottle is made for anyone who tops up oil lamps, refillable liquid candles or lanterns and wants a cleaner pour. Its one-piece LDPE construction keeps the internal delivery tube fixed in place, so the spout will not loosen or leak during repeated use. The 464.752 millilitre capacity supplies enough fuel for a dozen or more candle refills before the bottle itself needs refilling. Weighing only .141 kilograms, it is light enough to carry around the patio or keep in an emergency kit.

Adjustable Flow and Pressure Relief

An internal tube can be trimmed to set the exact flow rate you prefer, giving precise control when filling narrow lamp reservoirs. The wide mouth accepts bulk lamp oil, lantern oil or kerosene without funnels, while the cap design lets you loosen it slightly during storage to vent internal pressure and stop drips. Embossed graduations show the 500 ml fill limit; staying below that mark prevents siphoning caused by natural pressure changes. After each session, loosening the cap lets any fuel left in the spout drain back into the bottle.

Replaces Messy Funnels and Open Containers

This bottle upgrades from pouring straight from a bulk jug or using disposable funnels that spill on wood or painted surfaces. The sealed, reusable design eliminates the need for single-use plastic funnels and reduces the risk of overfilling individual lamps. It is not suited for buyers who need a larger bulk reservoir or a pump-fed system for high-volume commercial use. The jump is worth it when you refill several candles regularly and want a tidy, controlled process every time.
