Surprised that electrical tape works for labels. I personally use a paper label covered with clear packing tape. When I ran out of labels I just used a piece of paper.
OH! I would have used paper labels w/clear packing tape it I didn't have tape obsessed children in my house at the time

I am glad that worked out for me as I admit to being worried any condensation would destroy or distort writing on paper labels over a long storage in the freezer. I was/am worried someone would get into it not knowing what it was even though all my bottles are well labeled, tripled wrapped, poison warnings too and secured in locked ammo cases containing the original paperwork in my chest freezer. I figure if I die anyone going through my freezer is warned.
