This is a round wick with a uniquely braided cotton core designed with tension threads that give the wick a slight, but effective, curl during combustion. The wick is directional in that capillary action flows more freely in one direction. Due to their intricate design, the RRD series provides a centered burn pool, self-trimming burn characteristics, and a consistently high rate of fuel flow.
The RRD series works well with viscous fuels such as vegetable wax, gels, and one-pours. They are effective in containers and especially useful in pillars due to their concentric burn pools.
This wick for 2-3" containers, or double-wick in 4" and larger containers.
