Ice can be made from tap water, mineral water, or any other potable water.

Do not pour hot water.
Although the silicone is made of high heat-resistant material, it softens at high temperatures and may leak from the packing.
Please allow the water to cool to room temperature before using the hot water cooler.

Usually takes about 16 hours to produce ice.
This may vary slightly depending on the cooling capacity of the freezer, temperature setting, etc.

If ice is made with water droplets left over from cleaning, etc., they may stick between the case and tray.
In such a case, do not pull it out forcibly, but melt water or lukewarm water around the case for several tens of seconds, and then pull it out easily without much force by alternately and gradually pulling on the finger-holds on both ends.

If the packing is cracked during assembly, water may leak inside the case and the top of the ice may be chipped.
In this case, please melt the ice once, check that the packing is not cracked, and make ice again.

If the mold is oriented with the peak side up, air may not escape when pouring water and the peak may be chipped.
Check the orientation of the mold and make ice again.

If the mold is oriented incorrectly, large burrs may form. If large burrs appear, please check the orientation of the mold during assembly.
Normally, due to the high precision of the parts and the structure's ability to reduce the expansion pressure of the ice, only small burrs will form that will quickly disappear at room temperature.

Pouring water briskly will cause air bubbles to form in the ice as the water entrains air.
We recommend that you pour water slowly and give the water a light vibration after pouring to float air bubbles.

The white portion contains many impurities such as minerals, resulting in ice with a comparatively strong odor, but since it is derived from drinking water, it is harmless.
It can also be used for cold storage.

Can be stored in the freezer.
To prevent transfer of flavor, we recommend storing in airtight containers or bags.
The ice cream may have some frosting over time, but once the surface melts, you will be able to enjoy the clear ice inside.

If there is a large temperature difference between the ice and the beverage, it is more likely to crack.
Ice is cooled to about -20°C in the freezer, so waiting until it has defrosted at room temperature will prevent it from cracking.
It is better to keep drinks chilled to get closer to the temperature of the ice, so they are less likely to crack.

Silicone parts should be cleaned regularly with dishwashing detergent.
The surrounding polycarbonate parts should be cleaned with dishwashing detergent as well.
The dishwasher can be used (do not use the steam function). (Please do not use the steam function.)

Currently, due to manufacturing reasons, we are unable to sell ice spheres and ice cubes individually, but we will work to expand our lineup.
