These are replacement set of 5 Rollover Buttons posts C-587-6 for Games like:
Kings of Steel
as well as some older machines as these are no longer available - Purchase in the Premium White or Black or you can upgrade to a coloured option to customise you game a little.
This is a design that incorporates 5 rollover button posts like my single one with the only difference being that there is a branch tying them together to reduce the overall cost due to a reduction in the shapeways handling fee. You just need a knife to carefully cut the branch away from the base of the rollover button post.
Unlike another designers 10 pack which have a tapered shaft, this design are replicas of the actual original rollover to suit the metal clip.
