15.5oz Collins - StraightUp Glass

The 15.5oz size is spot on for a full pour over ice with a little room to spare, and the straight-up shape stacks neatly in my cabinet. The glass feels solid in hand without being clunky.

The straight-up shape feels sturdy in hand and the 15.5oz fill leaves just enough headroom for ice and a stir. Been using it daily at the counter and it's held up fine through repeated washes.

Bought a set for our cafe service and the 15.5oz size is just right for a proper collins pour without looking stingy. Only gripe is they don't stack as neatly as I hoped, but the reusable glass cleans up fine in the dishwasher.
