Christmas cracker party favors, new old stock English crackers made in Denmark

Three boxes (10 crackers each) of red and silver party crackers, for your holiday table.

We haven't opened any, and have no idea what they contain as the plain boxes give no clue - and we didn't want to spoil your surprise fun! (These are made in Denmark for the export market, so we wouldn't expect anything too naughty, or family unfriendly.)

All 30 crackers look excellent, though the boxes are a little worn. We didn't see a date marked anywhere.
