TWSBI ECO Fountain Pen ClearTWSBI fountain pens are beloved for their clear barrels (sometimes called demonstrators) that allow users to see the ink inside. The pen has an interior ink filling piston system that holds much more ink than a typical fountain pen cartridge. It also allows you to fill your pen up with ink without the use of a converter. Just unscrew the cap at the end of the pen, dip the pen into ink, fill, and screw the cap back on. The TWSBI ECO (for "Economical")

I suspect that they are lying about the ingredients in this product. I have never reacted to any skincare products except for chemical sunscreens. This product claims to be a mineral based sunscreen but I had a terrible reaction to it. I have an itchy, red rash all over my face and arms that's been taking days to improve. I can't help but wonder if they are not disclosing all of the components of this product. I will be returning this product and requesting a refund.
