I have reviewed a few pens on this site and pens are one of my frequent searches on crowd funding sites. So when you couple a pen with Titanium, I am instantly interested.
This was however an eBay find, but I believe it started its life on Kickstarter as a Titanium pen that accepts 35 refills without any modification. A plug and play pen : https://www.kickstarter.com/projects/klinkokids/ti-ballpoint-pen-stylus-refill-friendly-titanium-p
It was well funded back in 2014 – looking $10,000 and ending up with over $38,500.
If you got in early enough you could have picked up the early bird at $59. They currently sell for about $75 on their website.
I picked mine up for an absolute bargain price of £15 – brand new and unused on eBay! Result!
