Pacon® Super Value Poster Board, 22" x 28", White, 50 Sheets

good product, good price

This is hands-down the best and most versatile posterboard on the market. It is thick enough for projects and posters but flexible enough that you can cut it without difficulty. It is also much better priced than at office supply stores. I use this in my classroom for art projects and student posters for book reports, as well as for signs.
