I don't use expensive Avery labels for my DIY eliquid bottles. I just go to Dollar Tree and buy some of their inexpensive packs of usually at least 60 labels/pack. They have various colors, sizes, and shapes, and you'll find them in the school supplies section at Dollar Tree stores.
I write the eliquid name, PG/VG ratio, nic mg, and date I made it using a Fine Point Sharpie. I use them on bottles ranging from 30mL - 120mL, and they fit great! I usually also cover the label with a piece of clear packing tape so there's no way it can come off until I want it to. By the way, they also sell a small roll of that clear packing tape there, too, that comes on an easy cutting dispenser! Can't beat 60 labels and a roll of packing tape for $1 each + tax either!
