Fiber Wicks is 1000mm long. We have the fiber wicks in 3mm / 4mm / 6mm / 8mm / 10mm diameter wick.
The advantage of fiberglass wicks is that they generally do not burn in and must be replaced only rarely. We use the fiberglass wick in the burner for our flame eaters and stirling engines. The wicks burn with methylated spirits, lamp oil or wax in the Technical Model, however, should only methylated spirits are used as the alcohol does not smokes.

Of course, fiberglass wicks are suitable also for garden torch.
