Tare-Shield Mylar Reinforced Filler Paper, 5/16 Inch Ruled, 50# White Offset, 8-1/2 x 5-1/2 Inches, 100 Sheets per Pack (20985)

Good quality and exactly what I needed. A little expensive, but I could not find this size paper with reinforced edges.

Just what I wanted and have been looking for! So happy to have found this reinforced filler paper in the right size.
