Pocket heater with sticks in a very nice red velvet box. 1 of its ends remains lit between 9 and 10 hours, the 2 ends remain lit between 4 and 5 hours. WARNING: do not open during the first half hour.
Directions: Light the fuel rod at one end. Blow on it to get about 1 cm of lit fuel. For more heat, do the same at the other end. Once lit, place the fuel rod in the heater and then place it in the case.
