Are now available in specially marked boxes of General Mills cereals. The pens are skinny little things, reminding me of some skinny bobblehead pens that I received at Dave and Busters, but without the bobble. They are found only in the larger size boxes, so you do have to pay a little more. Also, there are 8 different pens available.

No idea what the chaser pen is (assuming with the other cereal promotions from yesteryear, the lightsaber spoons and pens, there was always a hard to find one) but the 8 include Yoda, Chewbacca, Mace Windu, Darth Vader, Anakin Skywalker, Boba Fett, Clone Trooper and young Obi-Wan Kenobi. So far the only box I opened (Golden Grahams) contained a Yoda.
