"Favourite" sealing wax by J.Herbin.
They are made from fine traditional sealing wax meaning they are fairly brittle and may not make it through the post without the protection of another external envelope.
For best results do not light the wick but rather melt wax in a spoon and pour onto the paper. This avoids the black carbon soot from discolouring the wax.
Each stick can be used to make approximately 10-12 seals (25-30mm).
Sold as individual sticks.
Colours may vary between batches.
