Reusable refresh! When heading outside, stay hydrated by carrying the Pirani Stainless Steel Insulated Tumbler. It holds 16 ounces of liquid and fits into all cup holders. Pirani has taken the classic red Solo Party Cup designand turned it into an eco-friendly, reusable cup. Did you know that every year, 500 billion plastic cups are used and discarded in our oceans and landfills? Yikes! It’s time to do something about this and choose something more sustainable, like this insulated tumbler. Even though the walls of the tumbler seem thin, they are triple insulated so you’re ensured of having hot hotness for up to 6 hours and cold coldness for up to 12 hours with no outside sweatiness. A vacuum insulated lid with a pop up sip hole is leak-proof and indestructible. You can actually wash the tumbler in the dishwasher, though it’s best if you wash the lid by hand. We hope you say no to single use and go with the Pirani Stainless Steel Insulated Tumbler!
