TWSBI ECO Fountain Pen - Irish Green w/ OnyxTWSBI 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")

Pretty, does come off easily
Color: Holo Silver Glitter Spray(2oz)
Works well. Glitter does come off pretty easily. If on clothing you can easily pat it off of you which for me was a con but for others might be a pro.

Spray bottle was defective...twice!!!
Color: Light Pink Glitter Spray(4.05oz)
Product itself was awesome...when it worked. The design if the spray bottle is awful. The first one I bought only sprayed once when we first got it but then the spray piece didnt work anymore and only sprayed air. I got a refund on it after I told them. I thought maybe I just was unlucky and got a defective one, so I bought another. Same thing happened, only the push down spray part got stuck after using it once and it just sputtered out air and clear liquid! I was able to get a refund a second time, but I'll be looking for a different company to buy from. Sad cause the one time it did spray out some stuff correctly it looked beautiful.
