I first saw the SmudgeGuard mentioned on the internet a few months ago and thought I’d give it a try. The price was right, and I was getting really sick of using a paper mask to keep from smudging my drawings as I worked. (The fact that I’m left-handed only made things worse.)
Now, having used the SmudgeGuard for a number of projects, I can say that I really like it. It’s well made, comfortable, comes in both left and right-hand versions, and does a great job of keeping my drawings clean. Plus, I look super-cool when I wear it. Recommended!
