LOVE the shamrock 40 oz tumbler!!!

It is so pretty! The clovers are 3D and the white background is shimmery. It hold ice for 24 hours for me. I love how the top of the straw is silicone, so when you bend it down into the cup and slide the lid closed, it doesn’t leak. When I want to use it, I take off the lid and thread the straw back through and drink. Plus it has a rubber bottom, so it won’t slip. This is my go to instead of yeti or Stanley., especially since they have the cool prints!


I love all these mugs! The quality and the efficiency of how quick I get my orders are amazing. My ice last over 48 hours and it is amazing!


I love my Home Run Mega mug. I get so many compliments on it.

Leopard mega mug

I was so surprised I got this in the surprise Mega mug. I love all my swigs. We did a test on other high brand cups and mugs. Turn them upside down. They all leak . But not the swig. Love all my swigs.
