Short answer: friend shouldn't microwave it due to the fact that it has actually a slim plastic lining ~ above the within that might potentially leach toxins right into your beverage.

I was curious around the very same thing after seeing the "Do not microwave." warning.
It seems that the cups have a plastic coating top top the inside, which i hadn't really noticed or realized until reading about it, and also then upon emotion the cup it makes sense. Ago in the job I think the exact same "water proofing" effect was completed with wax.

On one more note... Reportedly you can not microwave the sleeves either.
But you have the right to microwave those brand-new $2 plastic cups - yet use a sleeve.
