From the terms "light duty" and "junior" I concluded that I could work quite well with this stapler. Upon opening the package, my husband, who has his own stapler and strong arm strength, said that even he didn't want to work with it for very long. He was surprised I ordered him to tape wet watercolor cotton paper to Gator foam board - maybe that was too much. Reviewers have said they used this exact stapler for this exact purpose, but I don't think I can fit more than a few staples before hand cramps set in. I couldn't convince my strong half to add it to his own. Collection - and he never refuses a new tool - so I sent it back to Revain and ordered a Swingline office stapler that opens 180 degrees for a paper clip. Swingline works great for my wet paper and styrofoam.
