Drider silk - office conversation

As Joanna and Chloe returned to their cubicles, Chloe, being the wonderfully nimble person she is, accidentally knocked the large pile of files over on Joanna's desk. Send the thick manila folders sliding into Joanna's purse, and knocking that onto the ground. As it hit the contents of the purse were scattered across Joanna's cubicle, including the small envelope containing the silk. Chloe notices the small strange envelope and picks it up. "Hey, what's this," She said as she began to read the envelope. "What's... Drider silk?" Joanna finished picking up the folders and looked over at Chloe, "Oh, that's something I picked up at this weird shop on my way to work." She said, explaining where the shop was in relationship to her apartment. "Oh yeah, I heard of that place, it's that weird candy shop," She said as she turned the envelope over. "So you got this stuff there? I wonder what it is."
