This gear set includes the smallest gears: 6, 7, 8, 9, 10, and 11, as well as three tiny oval gears.
You can have one of this gear set for free when you order any other gear set at the same time. Just add it to your cart and it will be automatically discounted 100% to $0. This only applies to the first Tiny gear set, so if you want more than one the rest will be regular price.
For some reason there are cases where the automatic free discount is not being added to this item at checkout. There is now a option in the listing for a $0 Tiny gear set. Only one free tiny gear set will be provided with each order.
