Working in a scrapbook store I was able to try every adhesive out there. This is the one I always come back to after trying something else. It rolls smoothly without gumming up. The mount will not score your pictures or paper. I would definitely recommend this product! And bulk refills cut down the cost a bit. (Just a note, I prefer this angled tip over the more compact, older dispenser. Tombow has several similar products, so look carefully.)
This adhesive is my glue of choice. It works well for a variety of different applications and the rollers are easy to manipulate.
