The small pellets for the camp stove are over $20 for 24 of them. They burn for around 6-7 minutes.
These ones you get 38 for the cost of $6 and that’s NOT using all of the cotton balls (dollar store) or aluminum foil (dollar store). They are a tad bulkier but they do burn for a good 20+ minutes. You can make them the size you need as well.
