It started again just in time for the Grättimann season: the leaky paper bags (with the transparent plastic at the front) let the hail sugar trickle through wonderfully. It now spreads happily wherever the bags are carried or put down. This is very unpleasant at home, especially when half the family runs through and then spreads the sugar all over the house. Wouldn't it be possible to change the process so that the bags are sealed at the bottom?
