Ebisu Polypropylene Ice Tray 3 Trays 2 pcs Each

To keep my bottles cool

These are perfect for what I had in mind: they are a good size to make ice from either water, cold-brew coffee or tea, from day to day for separate take-along bottles, keeping the ice-trays colour-coded according to each liquid. They are of great quality and small enough to find a corner in my freezer.
