Bundle of 25 blank incense sticks. Make your own incense sticks with essential oils. 20 drops of essential oil makes 1 incense stick. Use a combination of oils, or any single essential oil.
Here's an incense stick recipe for inspiration:
5 drops frankincense
5 drops palo santo
5 drops vetiver
5 drops red mandarin
Lay an incense stick on a non-pourous incense holder and add the essential oil drops to it. Let it dry for 24 hours before burning.
