A Knit Blocker set consists of 20 units in a nice plastic storage case: twelve 8 pin Blockers and eight 4 pin blockers. Some projects may require more Blockers but the user can use string to extend the length or use individual pins in conjunction with the Knit Blockers. Of course, a knitter can buy a second set of blockers as well.
