This image shows a pale mass with a few dark spots on it. On the perimeter, the object is jagged. There are also vertical lines on the object, which are especially visible on the left side of the object.
The sample was taken from Page house room 143 in the California Institute of Technology from a white towel at 1:34 pm on 5/28/19. The sample was obtained by using a pencil sharpener on a Ticonderoga HB2 soft pencil to collect the shaving, and the shaving was then placed on a slide.
