If I ever have issues with getting these to stick it’s because the candle jar bottom hasn’t been fully cleaned. They work very well.

I have not used another type of sticky to compare this to but, these little guys stick!
I barely set them where they need to go and they are not going to move.
I can't imagine needing a bigger one either.
Be aware that once it is in place there will not be readjusting!

The only bummer is not being able to remove it after a burn to reuse the container.

Hello how you know what size to get?

I really like these saves me alot of time i see people having trouble with them i did one time until i started wiping my jar's with alcohol then they were good and i alway's have a tool to press down on it the stick better, never a problem after that.

The wick stickers have saved me so much time. There is no mess with messing around with a glue gun. They stick very well!!!
