I have been out of the fountain pen loop for a while and just purchased an eyedropper bottle of Noodler's Heart of Darkness. I don't have any empty ink bottles in which to store some for FP filling and wonder if storing ink in an orange plastic pill bottle (the kind that prescriptions come in) would be okay? My other option is to spill out a bottle of ink I really don't care for (I was going to add some black to change it to a darker shade) but if the plastic is not a good choice, I will spill out of the ink I don't like.
Thanks
