The 3M - Post-it® Tabletop Easel Pad, 20 in x 23 in, White with Primary Lines, 20 Sheets/Pad, 6 Pads/Pack is an incredible product that will suit many diverse needs. A conference on the go? A teacher's workshop? A business meeting in a place with no easel? No worries. This item has you covered and it also contains 6 pads for refills or enough to go around. This is super convenient and I wonder why nobody has thought of this until now. 3M innovation at its best.
