Harry Potter - Voldermort's Wand Original from Universal Studio Beijing

A key feature of Trelawney's wand is the prominent spiral groove or notch that runs along a significant portion of its shaft. This unique design element makes it easily recognizable and adds to its visual character.
The handle of the wand is described as being smooth and somewhat square-shaped, offering a different feel compared to more rounded or elaborately carved handles. Notably, there are runes intricately engraved on three sides of the handle. These ancient symbols often carry mystical meanings and further emphasize Professor Trelawney's connection to divination and the mystical arts
