TWSBI ECO Slate Blue w/ Onyx Fountain PenTWSBI 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")

Great dog toy
It's been played with and shook pretty good from a Border Collie and a poodle, no rips yet and it's been like a month.

Great lotion for very dry skin
Style: Updated Formula
I had a laser done on my face and the products they gave me weren't working. This came highly recommended so I gave it a try. I'm very glad I did! It moisturized my face really well without appearing greasy. I used the rest when my face got dry from winter (in th midwest). Felt very rich and smooth. Medium thickness.

This stuff is amazing! It has drastically helped repair my skin barrier. I had a flare up of dermatitis right before an important event and this helped clear it!
