Remixed from demerand's crayola compatible cap. I multiplied the number and then added center posts so it can hold a whole 10 pack set of crayola markers.
As an art teacher, I find that my younger kiddos tear up my taped together markers, but it's so much easier to pass them out as a bundle and it also keeps up with the caps as well. This may help the problem of the kids messing with the tape.
