PrimulaBuddy Silicone Tea Bag Holder, Easy to Use and Mess-Free, Dishwasher Safe, 4.25-Inch, Honeysuckle

Is this supposed to smell like the inside of a car that has been baking in the sun? I have the white & green one & it doesn't smell. My pink ones do.

Bought a white one and dark spots started forming underneath and have been slowly growing. Can't wash it off no matter how I scrub. Could it be mold?

Can you use this with any cup?

**seller** can i order green for sure? and how if i can ?
