The Xyron Megarunner refill I received fits my Teresa Collins pink version exactly. I like the light weight and ease of handling of this product and the adhesive is the best I have used.
These cartridges are so easy to load. It just drops right in.
I'm so happy with this new mega runner. The adhesive is super strong and easy to use. The mega runner gun holds a lot of adhesive but it's not overwhelming or uncomfortable in your hand. You will love it!
