Review on Dewel Classic Stackable BPA-Free Material by Joseph Hall

Although these mugs aren't official, I saved $10 instead of buying the overpriced original brand. To be honest they feel quite similar! The official cups are slightly larger than these cups (about half a millimeter larger in diameter), but that doesn't interfere with stacking. The durability is great too. I took these cups on a hike and they still work great. I've had these mugs for about a month or so and I think they're worth buying!
