National Artcraft's glass lamp oil insert is ideal for creating decorative oil lamps from almost any vessel.
The lamp oil is held inside the glass tube so there is no worry about leakage.
These inserts measure 4" long overall with a tube diameter that is 5/8" wide and a 7/8" diameter flange. These glass inserts are packed three (3) per box.
In business since 1949, National Artcraft is a name you can trust.
