This is a listing for a full set* of 6 spiders! You can individually choose 6 pins from the unlocked pin designs, so this pricing reflects that. If more than 6 designs are unlocked, others can be added via their own respective add-ons. 

*Even if less than 6 designs are unlocked, by keeping this pledge tier you are still agreeing to pick and choose 6 total spider pins from unlocked designs.
