Amazon Must Have that will blow your mind. 🧊 Comment SHOP and I'll and you a DM with the link. Or click the link in my bio. This is one of those products that I wonder where it's been all my life. Or at least my life while owning a tumbler 😉 I love cold water. So this is a must for me. You simply place the smallest, or 1st ice cube into the tumbler first, followed by the 2nd then 3rd. It has kept my water cold for hours and through several refills. I HIGHLY recommend this if you're a @stanley_brand guy or gal.
