To select a design, press the top and bottom of the stamp together. While holding them in place, press the red lock button on the side of the stamp. Then turn the ridged wheels on each side of the rubber stamp pieces to align the design you want with the notches in the stamp's clear base.
This stamp includes 12 designs, one for each month. Each design is approximately 5 mm tall and 20 mm wide. For best results, we recommend stamping lightly when first using this stamp.
