Let's just address it head on — yes, our glasses cost more than the ones at the big box giant down the road. And no, we're not going to apologise for that. Here's what you're actually paying for.
First — what even is borosilicate?
Most glasses you've owned in your life are made from soda-lime glass. It's cheap, it's everywhere, and it absolutely loses its mind if you pour hot coffee into a cold glass. You've seen it. Maybe you've lived it. Sad, expensive, slightly dangerous.
Borosilicate glass contains boron trioxide — which sounds like something from a chemistry exam but basically means the glass expands and contracts at a dramatically lower rate when temperatures change. Hot espresso into a cold glass? No drama. Freezer to microwave? It genuinely does not care.
This is why it was originally developed for laboratories. And why it's now the material that lets us make glasses that look like this.

Those little jewel-toned orbs fused to the side? Impossible to achieve in standard glass without the whole thing becoming structurally dodgy. Borosilicate holds its nerve — which means we can make something that looks genuinely unhinged in the best possible way, and you can actually use it every single day.
It doesn't cloud. It doesn't fade. It doesn't lie.
Cheaper glass goes cloudy after a few months of dishwasher cycles — that slightly greasy, milky look that makes everything feel a bit sad. Borosilicate stays crystal clear and colour-true for years. Those amber and teal tones aren't painted on or coated — they're fused into the glass itself. They're not going anywhere.

It's non-porous and lead-free.
Your coffee tastes like coffee. Your wine tastes like wine. Not like glass, not like whatever the previous drink was. There's a purity to drinking from borosilicate that you notice immediately and then can never un-notice. Sorry about that.
The honest bit
Choosing borosilicate is a rebellion against disposable decor. It's the difference between buying something you'll replace in eighteen months and buying something that outlasts the trend, the house move, and honestly probably several relationships.
We don't stock anything at Missy K that we wouldn't genuinely want on our own shelves. These glasses made the cut because they're beautiful, they're brilliant, and they make your morning coffee feel like a small ceremony worth showing up for.
That's worth a bit more than the ones in the bargain bin. We reckon you already knew that.
These aren't one season pieces saved for the "good cupboard". Missy K is anti "saving it for best". Life is the occasion. Use the good glass.
