Vacuum tins can be hard to open. We recommend using a short, stubby flathead screwdriver. Insert the flathead under the lid and twist. It may take a few hard twist to break the vacuum seal of the tin.
If you do not have a flathead screwdriver, a stout butterknife or handle end of a spoon or fork will also do. Insert under the lid and twist. It\’s OK if the side of the tin gets a small dent. Do not use pliers.
