Incense making kit. There is overwhelming evidence to support the lack of ethics found with incense production. Terrible working conditions in impoverished areas of the world. Zero-regulation means that unethical incense makers will use wood waste and other dangerous materials/chemicals to cut costs, increase profits, and grow their wealth at the detriment of their customers.

I find people who have a history of being allergic to cheap incense bought at tourist shops or "Bob Marley" type sales booths have absolutely no allergic reaction to my natural incense. If you think about it, having your eyes turn red and water, your throat itch, and your lungs feel wheezy is a totally healthy reaction to incense that has dangerous materials/chemicals in it.

Creating a kit that allows people to trust incense and make "whole herb" incense (David Oller's term) would bring Incense back to what it used to be.
