I use the small stickers for all my wick/jar sizes (tealights to 12 oz.) so that I only have to buy one size sticker, and they work great with everything! They are so easy to use that my 7 year old helps me wick with these. I saw in previous comments that they don't stick. That's true if your jars/tins are too cold, but if they are at least room temperature, they stick just fine. If I store jars in my attic over the winter, for example, I have to heat the jars before applying the stickers. They also won't stick if there is any residue on the bottom of the jar, such as when I am reusing an old jar for a new candle. Just be sure jars are completely clean. Those are the only two cases I have found where they don't stick, but it's very rarely an issue as most jars I use are brand new and stored at room temp.
