Is En Tree (ISNTREE)'s "Ultra-Low Molecular Hyaluronic Acid Toner Big Hit Thank-You Set" went on sale on Saturday, October 10, 2026, in limited quantities. It is the second Japan-exclusive special set, announced by TYCHE LLC on October 9.
It combines 300 mL of toner with one sheet mask (25 g), with a manufacturer's suggested retail price of ¥2,310 (tax included). It is sold only in stores at variety shops and drugstores.
A 300 mL toner combined with one sheet mask
The set contains the "Ultra-Low Molecular Hyaluronic Acid Toner" and the "Ultra-Low Molecular Hyaluronic Acid Sheet Mask." The toner is the same 300 mL as the one sold on its own, and the mask is one sheet of 25 g.
The company describes the set as a project made in gratitude to those who bought the toner. Aimed at the dry winter season, it is offered as a set that combines the toner and mask for daily moisturizing care.
The sheet mask is sold on its own in two sizes in Japan-exclusive packaging
The sheet mask launched in April 2026 in Japan-exclusive packages of one sheet and three sheets. The set this time includes one sheet.
The manufacturer's suggested retail prices for the individual items are ¥2,310 (tax included) for the 300 mL toner, ¥275 (tax included) for one 25 g mask, and ¥825 (tax included) for three 75 g masks. The price of the limited set is the same as the manufacturer's suggested retail price of the toner alone.
The individual items are available on the Rakuten Ichiba page for the Ultra-Low Molecular Hyaluronic Acid Toner and the page for the Ultra-Low Molecular Hyaluronic Acid Sheet Mask. This limited set is sold only in stores.
