Okay, I confess I'm a highlighter addict. My books are lovely shade of pink after I've finished reading them. I used to use the pink markers by this same company, but could never find them when I needed them. A clerk at the local Christian bookstore suggested I move to the Bible Dry mechanical pencils, and I finally did so, only to have the same exact trouble. I ended up with about six of the pencils and no leads. Pink leads were always out of stock, and the store didn't seem interested in ordering bulk of the leads they obviously went through fastest. I wrote to the company that makes the pencil, and they directed me to CBD. I ordered 10 of the leads, and they arrived in days. If you have the same problem I did with locating a local supply of these leads, this is the only real solution I've found. I'm very happy with CBD.
