Burning sand wax olive

Very fine wax granules that eventually burn like a candle.
You fill a glass or jar (heat-resistant) with these granules and insert the wick in advance. The fuse must have an iron plate at the bottom. Trim the fuse if it is too long.
This item comes with 2 fuses. For a glass measuring 8 x 9 cm, for example, a weight of 50 grams of granules is sufficient.
With 400 grams it can be filled 8 times.
