ThermoWeb is my favorite tape runner. I love it because you can run the tape fast or slow over your paper and it will always work.(some you can only use at a snails pace to get it to adhere properly.) I also love that you can you run it straight or curvy down your paper, as well.
I have used this runner for the last 5 years and I wouldn't use any other. I love how is curves and turns makes it so easy. I also love that you barely have to touch it to the paper, there is no pushing it down it just glides across.
I have purchased this six-pack of tape runners from scrapbook.com all many times over the years. This product never disappoints, and the price can't be beat. I highly recommend it.
