SCHMIDT 12 Pack - Ball Point Refill - Black Ink Medium P900 Parker Style

These may not dry out prematurely, but in all my years buying Schmidt refills in bulk, all came with blue or black plastic caps to prevent drying-out during storage. I will go with another vendor in the future. They were a decent price though.

All OK

I found these to be affordable and for the price that adds value to my pens sales, well worth it.
