Query: neat piece but substantially smaller than described.

I like malaysian driftwood, it sinks immediately and usually comes in interesting shapes and doesn't seem to discolor water as much as other driftwood. The piece I received fit that description, however the seller seacorals claims their medium pieces are 10-15" long. I was expecting maybe 12" or so. The piece I got is barely 8" at its longest measurement, and doesn't take up much room in my 6 gallon tank. I am disappointed as this means I will have to buy more of it, since I wanted driftwood to be the focal piece. I will be ordering a large next time.
