Just got 2 of the wave glasses and one has broken after putting an ice cube in before the liquid. We contacted customer service and here's the response:
"I'm sorry to hear that one of your Pink Wave Glasses has broken.
Whilst our glassware is durable and dishwasher safe, unfortunately dropping a hard ice cube into a glass can lead to a breakage happening.
We do mention this on our website, as well as the outer packaging that our glassware comes in and the packing slips sent with each order to not put ice into the glassware before liquid. I'm sorry that we won't be able to replace this piece for you, we also do not offer single glasses for purchase.
Thank you, I hope you are enjoying your week."
So $40 down the drain. Will not be ordering again.
If you're thinking that maybe I was a bit rough with the ice cube, I can assure you that my hand was below the rim when I let go of the cube. This is obviously a bigger problem as they also so this on their website:
"Do not put ice into the glasses and carafes before liquid as hard ice cubes may cause damage to the glass. Always be gentle when placing onto hard surfaces."
