sleek
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">smooth and shiny</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for sleek that I've seen before include "Lustrous" , "(Of hair) smooth, glossy" , "Smooth - well-fed" , "With a smooth, gleaming surface" , "Aerodynamic, streamlined" .)
