Support the NAISU N1 Ice Diamond Edition!
We’re excited to introduce the NAISU N1 Ice Diamond Edition, building on our success with the N1 Ice Ball Edition, which was fully funded in just 3 hours on Kickstarter!
We’ve delivered on our promises on time, and now we’re ready to take on a new challenge: creating the largest clear ice possible with our innovative N1 clear ice maker.
Why the Ice Diamond Edition?
The N1 Ice Diamond Edition produces a stunning 185g clear ice diamond—53% larger than the original 65mm ice and an incredible 100% larger than the standard 60mm spheres found on the market.
Bigger ice means better cooling, less melting, and minimal dilution, giving you more time to savor your favorite drinks.
In fact, one diamond may be all you need for a whole evening!
What's the same?
World's most compact clear ice maker - reloaded
Check out the full product benefits from our previous campaign's video!
NAISU N1 easily fits within your freezer door.
Using 304 stainless steel inner and outer wall vacuum tumblers, we are able to get the maximum insulation in a slim form factor. That gives the N1 excellent directional freezing capabilities, helping us to make clear ice in colder freezers with a fast turnaround time.
The steel inner liner is made with hydroforming weldless technology. Ensuring a strong, seamless liner that is strong, durable and releases the ice easily.
Self-Ejection technology
NAISU N1 ejects the mold from the tumbler when the ice is fully frozen. This acts both as a freeze indicator and facilitates ease of removal.
No more uncertainties about when your clear ice is frozen.
No more pulling out half frozen clear ice after a whole night of freezing.
No more struggling to pull ice molds out of the insulator.
All with one elegant innovation by NAISU.
Simply twist to release
Other products can feel like you need multiple hands just to fail and remove the ice.
Crystal Seeding Technology
NAISU N1 employs Crystal Seeding Technology, inspired by Czochralski method used to make pure silicon wafers for the semiconductor industry. It allows for rapid crystallization without cloudiness.
In-house tests have shown that NAISU N1 reduces total dissolved solids in the clear ice by over 87%. Reducing 88ppm dissolved solids in the source water to 10ppm in the clear ice section.
N1 effectively purifies the water in the clear ice section, giving you a purer taste for your drinks.
Safe materials
We use trusted factories to manufacture the N1 to our high standards. In our previous campaign, we've sent random samples of the previous N1 to laboratories in Japan to certify that the product meets or exceeds FDA food safety requirements. It passed with flying colors.
Part of the JRFL testing report of the NAISU N1 sphere edition.
As part of our Japanese partner's due diligence, about a dozen N1 samples were sent to Japan's JFRL laboratories to certify for food safety. We're glad to say that the N1 tumbler, mold and caps all passed JFRL's thorough and stringent tests under FDA for leaching of chemicals.
JFRL is an ISO 9001 certified laboratory and have established and is operating a quality management system. They also obtained ISO/IEC 17025 and JNLA laboratory certifications to part of the test items.
Going above and beyond
For the NAISU N1 Diamond edition - we will be using LFGB European standard certified - platinum silicone. Raising the standards on NAISU N1 products.
What's different
Apart from the clear size enhancement of the clear ice - the ice diamond is beautiful to look at. It will be the centre of attention at any parties, when you are entertaining guests.
The ice diamond is created at the conjunction of popular demand, going against the tide and yet yielding to good sense.
At the end of the N1 sphere ice campaign - many backers reached out asking for cubes and block ice that can be used for highball, cocktails and other drinks.
We want to give our backers what they want to use the ice for, but not the shape that they want.
We resisted that idea for several reasons. Cubes and blocks do not fit well into the N1 tumbler and end up with a lot of unused space. This means using a lot of silicone which is wasteful in materials and shipping carbon footprint. It also goes against our design ethos of being the most compact clear ice maker.
Making a cylinder or a tapered cylinder (kind of like a carrot) - would be a more efficient use of space. But it would definitely look odd.
We finally settled on the ice diamond.
Inspired by the gastro bars of Tokyo, the ice diamond looks trendy and amazing. It has sharp facets that refracts light beautifully, showcasing and elevating the drink.
It is also immediately identifiable from generic cubes and blocks commonly found on the market.
We hope you enjoy the latest creation by NAISU, by the 91 Percent Company.

How to make clear ice?
Here's a tutorial video on our Instagram page on how to make clear ice.
https://www.instagram.com/p/DAXxoJBS_Or/
Step by step instructions below:
- Ensure the silicone mold and tumbler is thoroughly cleaned with soap and sponge. Taking care to rinse of all residues from the surfaces
- Fill the tumbler with water to the shoulder line
- Place the mold very slowly into the filled tumbler. Not much water should overflow out of the tumbler if done sufficiently slowly
- Knock the sides of the tumbler to release trapped pockets of air
- Press the mold slightly into the tumbler. Some water may be released
- The top of the mold has a little funnel shape. It should have an excess of water there to ensure proper freezing
- Place into freezer
- Remove the mold when it has ejected and gently peel the mold off the ice
- Let ice stand in glass for a few minutes to temper. This prevents cracking when your drink is poured in.
- Enjoy!
How to make super clear ice?
Making super clear ice is not rocket science. It comes down to a few basics.
Pure water - water used should be as pure as possible.
The two key sources of contamination are Total Dissolved Solids (TDS) and Dissolved Gases.
TDS refers to the amount of dissolved salts in the water. It can only be removed by two methods - Distillation and Reverse Osmosis. Filtration is not a method to remove TDS. In fact, certain “water softening” filters adds salt to the water, to precipitate out calcium. In the process increasing TDS.
Dissolved gasses refer quite simply to gases, such as air and nitrogen dissolved in the water. The main source for dissolved gases in tap water is in line aerator - taps which produce a lot of bubbles. Another source of dissolved gases is the source of the water. For example in Palo Alto, California, we seen tap water emerge completely chalky with tiny bubbles which clears after standing for a while.
How do we get pure water?
NAISU N1 is designed in Singapore with tap water standing at around 100ppm with low dissolved gases if aerators are not used. Typically we use tap water and achieve crystal clear ice.
If your region suffers from high TDS, we recommend using bottled distilled water or reverse osmosis water.
Ice made from bottled water will exhibit large bubble streaking due to the bottling process which pressurizes the bottle to give it structural integrity.
The large bubble streaking does not affect taste. We recommend leaving it alone.
To achieve clear ice without streaking - the water can be boiled before use, or the bottle can be opened and left to stand for a few days before use. Both will reduce the appearance of bubbles significantly.
