Tip if you're looking for a quality pen as branded swag/supplies for your business:
When you find a pen from another vendor/restaurant/etc that you LOVE, take a few minutes to find who ordered them and get the same supplier/SKU. They'll gladly share that info in my experience.
Bulk pen quality is so over the map, even when it claims to be the same model number, I've found it to vary among suppliers.
All that being said, I've lost who we got ours from and can't recommend one myself!
