Review: Solid 10/10 - I bought these for my simply modern tumbler and let’s just say I am one happy gal! The size fits perfectly for my tumbler. The quality is sleek and simple which I love. It’s plastic material but strong for liquids even coffee And the different colors provide options for whatever look I’m going for each day All in all, these replacements straws are amazing!
Review: Fits Securely and Works Great - This is a solid replacement lid that fits exactly like the original. My first one accidentally fell off the dishwasher rack and melted, so I was really glad to find this replacement available. The fit is perfect, it snaps on securely, and it works just as well as the original. It’s always frustrating when a small but essential piece breaks, but this lid solved the problem without hassle. I’m very pleased with the quality and would definitely recommend it for anyone needing a replacement. TL;DR: Perfect replacement lid — fits like the original and works flawlessly.

### ⭐⭐⭐⭐⭐ Boot works well.
*by B***0 on March 3, 2025*

I like this boot. It fits nicely on the Simple Modern design mugs and has stayed on for weeks. It protects the bottom from getting dented or banged around. But the best part is it keeps the mug from slipping. It is not easy to tip over due to its silicone smooth texture. I like all the colors choices, even though I went with white. I would like to see the color choices expanded some more. Great purchase to proceed these expensive mugs.
