Stainless Steel Cups, Set of 4 16oz Drinking Cups, Stackable Beer Cup, BPA Free Healthy Metal Cups ◕‿。

Love these! It feels as though cold drinks stay colder and taste better in these cups; my guess is because they don't absorb any detergent taste when they are washed. I typically don't have breakable tableware in my house (helps kids develop confidence about setting the table and dining when things don't break), so these are a nice step up from plastic cups.

Spend the extra $2 and seek out the I've that's electric polished inside. This one is a little rough on the inside and I'm concerned about things sticking to the bottom with use.

Perfect stackable and strong. Use for mountain bike trips. Perfect to add your logo or sticker.

I would like a glass before, but the glass has a fatal weakness is fragile, not just drop on the ground, but sometimes after washing the glass with cold water, then pour the boiling hot water in it unintentionally, then tragedy happened...While stainless steel cup will not, even if it stay in the refrigerator before, you pour boiling water next, it is safe! This is awesome, I think I will buy more stainless steel cups, rather than the glass.
