There is only one way to make these chunks of natural beeswax - to harvest it from beehives. We let the apiarists do that for us. Each little chunk goes a long, long way in preventing threads from tangling.
Pull your thread across the beeswax chunk before using it and it will also strengthen your thread and prevent rotting of natural threads. This is a must for any serious beading enthusiast - especially if you are reproducing vintage pieces!
Two chunks are illustrated for variability. This is a natural product, so please expect some variation.
