Swarovski

Swarovski is  Czech maker of fine crystal products, including pens. Their pens are usually shipped with Schmidt D1 refills. Any D, D1 refill should fit their pens. You can purchase D1 refills that include the plastic knurled cap (similar to a Cross style refill), or you can use the one that came with your pen. Some pens have a sleeve with the cap already attached into which you slide your D1 refill.
