The cone holder for your bench will be made from the same wood your bench is made from.  It sits ontop of the bench pocket when the bench is at the higher levels.  It can be used on the bench if the seat is set at the correct height or it can be used without the bench.  It's handy to store on top of the pocket on your bench.  
This add on must be purchase at the same time the bench is purchased so the fit will be perfect.  This listing is for the cone holder only, the bench is not included.
If you have purchase a finish for your bench your cone holder will also get a finish, otherwise it is unfinished like the bench.
