Collapsible Silicone Coffee Cup,Aonesy Food-Grade Portable and Reusable Folding Mug for Travel Outdoor Camping Hiking Picnic, BPA Free&Leak-proof Lid Design(Pink)

Bought this cup to take with me on my long morning commutes. I tend to carry lots of item with me to work and I tend to find myself not to have a lot of room in my purse for a big coffee to-go cup. Love how this collapses and fits perfectly in my bag. It was a nice pink color until I noticed the coffee has began to stain the cup. It is also a little flimsy and has developed a smell to it, as any silicone item would. Is very convenient for travel or women on the go but silicone material probably needs to be improved to avoid staining or catching smells.
