This is the best material available for a didgeridoo mouthpiece.
Beeswax is an inert substance, which means it is chemically inactive.
It is virtually impossible for bacteria to grow on beeswax, which is why the world's oldest known culture (that of the Australian Aboriginal) has used it on didgeridoos for thousands of years.

Being a natural disinfectant, using a beeswax mouthpiece ensures that your didgeridoo will discourage bacterial activity and reduce the possibility of cross-contamination. Bacteria simply will not thrive in such an environment.
Not using beeswax mouthpiece is health hazard, specially if you share the didgeridoo.

Directions for use: Heat the beeswax in very warm water for about 3 minutes. It will come out soft and pliable, like firm play-doh. Break the beeswax bar in half and roll it into a cigar shape about 4 to 6 sixes in length, depending on the circumference of your didge at the mouth end. Apply the beeswax cigar to the top of the mouth end and pinch the beeswax down into the wood on both sides of the mouth end (inside and out). This forms an air-tight seal and fixes the beeswax to the wood. Keep applying until the ends meet. Adjust to suit your mouth shape and WALLAH ! - you have the safest and most practical didgeridoo mouthpiece available!
