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")

Puppy seems to love!
Color: 20 Pack Rabbit Style
Purchased to have when we brought new puppy home. This is perfect for her teething needs. I think she plays with container as much as the toys. As stated, these are toys for a puppy or smaller breed.

Not for Malinois
Color: 20 Pack
Chew resistant not so great. Not durable enought for a 5 month old Malinois. Still cant find a toy durable enough and he's now going to be 15 months.

Objects are smaller than they appear
Color: 20 Pack
I bought these to donate to a dog program at work. I was so disappointed when I opened the box and saw that they were so small. I hate when the adds make items look larger than they actually are. On the flip side, this would be perfect if you have small dogs.
