①Water and calcium hydroxide are added to konjac flour, and the mixture is stirred thoroughly.

If lumps or air enter the mixture, the product will be defective. Therefore, this sensitive stage of the production process is critical to quality control.



The mixture is quickly poured into the mold.

This process is done carefully, one by one, to make sure no air bubbles get into the mixture. Liquid konjac hardens rapidly, so if poured too slowly, the product will be deformed.

The molded konjac is placed on large racks to solidify over time.

The konjac remains in a jelly-like state, but it will coagulate and harden slowly over time. This process produces konjac with a firm, pliable texture.

The konjac is boiled for a few hours to harden.

While the konjac is being boiled, it undergoes an alkali heat solidification process that makes it ready to eat. Heat reaches the inside of the konjac, and boiling continues until the solidification process is complete.


The konjac used for our sponge puffs is complete.

The konjac is hot, so it needs to be slowly cooled in a tub of water. Slowly cooled konjac becomes a high-quality sponge.


The sponges are freeze-dried (unfortunately, we can't reveal this process).

The freezing and thawing process is repeated in a special freezer. Unfortunately, we can't reveal the details of this proprietary technique.

The basic process is as follows:
(1) Freezing separates the water and solids (konjac fibers), and the water becomes ice.
(2) When thawed, the parts of the sponge that contained ice become spacious.
(3) The originally elastic konjac fiber remains and becomes a sponge.

Thawed sponges are placed into a drying room.

Thawed sponges are washed with boiling water, sterilized, then dehydrated, and then moved to the drying room. Drying them slowly ensures that they do not deform. This is another key to high-quality konjac sponges.


The sponges are packaged, and the process is complete.

Each sponge is examined via our quality-control checklist for:
(1) Scratches and foreign contaminates
(2) Deformation and discoloration
(3) Actual measurement of size and weight
(4) Actual measurement of pH and Tu values, etc

Now it's your turn: Rehydrate the sponge with hot water, it will become soft and absorbent.

When you receive your sponge, it will look and feel stiff. If you put your sponge in hot water at about 40ºC, which is the ideal temperature for bathing, and rub it lightly, it will swell to about 50% of its original size and become a soft sponge. Please enjoy our product and give your precious skin the care it deserves.
