I have used this product since I started scrapbooking 13 years ago.
Now I know it did it wrong
I've used this adhesive for years. It's my old faithful adhesive. 49 ft is $4.50 to refill. Compare this to $8.50 for Scotch dot adhesive refill. You have to thread the Herma manually thru the reels. The Scotch is a drop-in cartridge. Just depends if you want to take the time to refill the herma, which can be tricky the first time you do it.
