Set includes one block of each size: 1"x1", 2"x2", 3"x3" and 6.5"x2". Complete with grid lines for easy stamp alignment! Unless you stamping while sitting on the Golden Gate Bridge on the foggiest day of the year, you will have no problem placing the stamp exactly where you want it! Whether you have five stamps or 100, this set of blocks will take care of most all of your rubber stamping needs!
BONUS! Hint: To achieve very detailed stamping with the cleanest, most crisp lines, place a soft computer mouse pad, or mat underneath your work while stamping. OR YOU CAN USE THE REALLY WONDERFUL Mat we INCLUDED with these 4 blocks! LOVE IT! Thanks SimonSaysStamp!
