Each digit (0 – 9) is provided on separate cards, each featuring 3 rows with 15 columns and 7 stickers per column (a total of 315 individual digits per card). The columns are perforated in such a way that either a 6-pack sticker and a single digit or two 3-pack stickers and a single digit can be removed. Of course, you can also cut out 315 individual stickers from a card using scissors.
