What paper cups does can be used for both cold drinks and coffee? I see a coffee shop named Blue Bottle use their paper cups for hot and cold drinks. I wonder what paper-cup tech this is?

In my shop experience, using hot cups for cold drinks make them soggy. I'd like to get onboard with their manufacturer, because I don't want to have to keep two kinds of cups!

I wonder if anyone knows. Thanks!
I don't know that company, but I assume insulated paper cup is what you are looking for.

You may have a quick Internet search for brands and whole sellers.
