Corkcicle
Bottle ice cube mold
$25
For elongated ice cubes that fit nicely in your water bottle.
Have a smaller bottle or want to use it for glasses? There is a notch in the center of the sticks for you to break it in half easily.
Made of quality BPA-free silicone, there is a metal rod inserted all around the mold so that the journey between the sink and the freezer is mess-free: you can hold the mold with one hand without it bending or twists.
Makes 4 sticks of 6"/15.24cm.
