This is a bulk pack of YATE solid fuel tablets for hexamine-type folding stoves, 200 g total made up of 8 g round tablets — roughly 25 tablets, enough for extended trips or a base-camp supply rather than a single weekend.
As with any solid fuel, output is lower and slower than gas or liquid stoves and burning leaves soot on pots, so it works best as a lightweight backup fuel or for short boils rather than daily two-meal cooking. Buying in bulk makes sense if you already use a hexamine stove regularly and want to avoid restocking small tube packs on every trip.
