This set of gears is collected to fill in some of the thematic gaps that other gear sets have left. There are some double dense gears, some off-center rings, series of hoops in some pretty small increments.
This package contains 3 large gear sets.
Page 1 has hoops in 16 tooth increments as well as a bunch of double dense and offset gear in gear shapes. Page 2 has a large set of 20 tooth increment hoops and some small double dense gears. Page 3 has some larger double dense gears as well as off center hoop gears.
The hoops in page 1 and page 2 are quite thin and as such easy to break if handled roughly.
