Round Orange pill with "K" inscribed

[lauraj]

I need to identify a pill. I have never seen any pharmaceutical pill like this before. It is a bright orange round pill and the only inscription on the entire pill is a large "K" on one side.
Anyone know what this is?

I can only find this in one database, so it's not confirmed.

Round, orange pill imprinted with K (the upper arm of the K has a little arrow on it) is 325 mg enteric-coated aspirin.
