Pentel Tradio EnerGel Combo Gel Ink Pen - Soft Rubber Body - 0.7 mm - Yellow Body - Black Ink

appearance of pen - looks like a more expensive pen and feels good in the hand. the outer body does not feel 'rubbery' at all but does have a slight texture to it. it is not perfectly smooth as glass or metal would perhaps feel.

the one nit-pick that I have with this pen, is there is a clear plastic ring that separates the two 'halves' of the main pen body. IMO this clear plastic ring is very cheap-looking. I would have been more impressed with the appearance of the pen had it used a black or 'chrome' looking part instead. the clear plastic ring is just above the 'chrome' looking part in the photos.

We learned that the spring in the body CAN be removed by hitting the body lightly against your hand until the spring falls out, thereby allowing you to use the standard Tradio refill.
