Stanley Who???

This is my favorite Swig yet!! I’m already a big fan but I drink a lot of water and needed something bigger. The design is great! The handle is comfortable and make it easy to carry. The bottom fits perfectly in my jeep cup holders. It may be hard to tell in pictures but the background for wild child is the sparkly diamond white. A+ all around!

“OMG, Becky! Look at this swig! It’s so big!” Seriously though, I love this 40 oz Mega Mug. It says it keeps drinks hot for 9+ hours & cold for 24+ hours, but I believe it’s longer. Love, love, LOVE my swig mega mug! Will definitely be recommending to friends and family! PS: Over the Rainbow is the design I have.

Been waiting on that 40oz Mug

I received my email today that the 40oz Mug has arrived. I ordered two Mugs one Hot Pink and one Wild Child. I’m looking forward to the large mug with a handle that will fit into my vehicle.

Mega mug

I love love love swig cups, I ordered 2 and can’t wait for them to come in. Will update or post another review once I get them in. But I just know the handle is going to be a game changer.
