They can be really tough to remove, but a quick fix, set the jar in the oven at 200F till the jar is hot and the glue will soften and come right out. HTH SharonH And this is so much cheaper than paying $20!!!!
I used to buy wick stickums all the time. I had heard several candlemakers say they used glue from a glue stick with a glue gun, but I never could get that to work for me. Until one day I ran out of stickums and decided to give them one more try. Sure enough the glue sticks worked very well. I buy a bag from Walmart and they last a year. Bag cost $.99. Don't those stickums cost $20? SharonH
