The weight of this pen is perfect. It feels heavy enough that it won't easily break and the ballpoint ink glides smoothly across the page. This pen will work with most standard refills. Green & Lyme is an authorized retailer of PenGems. We've chosen to partner with PenGems because they produce the most beautiful and high quality crystal pens we've ever seen. (And we've tried a LOT of pens!) These crystal pens make for wonderful gifts and if you are anything like us, you'll love collecting them all!
