Pre-cut 10'' x 10'' GRAY vulcanized fiberboard material for pickup makers. Perfect size for cutting your own bobbins.
*** NOTE*** Fiberboard material has a natural tendency to warp. Even though we send the material perfectly flat, we cannot guarantee it will arrive to you perfectly flat. This should not however affect the final assembly once everything is held into place with magnets and such.
