TWSBI ECO Transparent Yellow 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")

Disappointed in this purchase. I have purchased this type of shorts for sleep wear in the past and enjoyed them but the quality, fit and sizing has become increasingly unpredictable. This batch is so bad they fall off while I am sleeping anytime I turn in the bed the item slips off of my body. The elastic is so tiny it can't adhere to my shape. It cost too much to return the item so I am using it till I find a replacement.

Soft, but too short for my long legs

Size: 10, Color: Basic Pack

These are soft, but much too short in the legs, so that I have to continuously pull the legs back down out of the crease between my upper thighs where it creeps up into the crease btwn the thigh and stomach. If they were about 4-5" longer they would be a 5☆ rating for me.

NOT COTTON PANTIES!

Size: XX-Large, Color: Multi Colored

The site said the panties are 100% cotton. LIE! They are some horrible stretchy material that is most likely a petroleum product. ie polyester or some man-made horrible material. The colors described on the site were very light pastels. LIE! The colors were hardly bright- dull, ugly muted brownish colors. UGLY! Don't believe the site. Don't buy these panties if you adore cotton!!!! Caveat Emptor.
