Stasher Wire-bound One-Subject Notebooks include a storage pocket built into the inside of each cover. They are perfect for focusing on a single project and note-taking. Smooth, white, 15 lb. writing paper is college-ruled with a red margin line. Ends of the tin spiral wire are coil-locked for snag-proof performance. Covers are made from 15 point genuine Pressboard and come in four assorted colors. Each 8-1/2" x 11" book contains 100 sheets of perforated paper and is three-hole punched along the 11" binding edge so it can easily fit inside letter-size, three-ring binders.
