Purchased in November 2025 at a store in Ikebukuro for ¥2,970 (tax included). It's a great deal as shipping is included. I bought it intending to use it, but I don't think I will, so I'm selling it while it's still in good condition. I have stored it carefully in a dark place since purchasing. ●Product Description Quoted from the official website below: ◇This is a care product specifically for soft vinyl dolls. Soft vinyl is a soft polyvinyl chloride (PVC). It is not effective on materials other than soft vinyl. This is the material used for the heads of common dress-up dolls. ◇Sunlight is required. UV curing lights for resin are not effective. "Stain Care" is a doll-specific stain remover born from a doll hospital. You can remove stains from dolls that you've given up on until now. Please use it after removing dirt with a doll cleaner (neutral detergent is also acceptable). ※Just apply it to stains you are concerned about, such as ballpoint pen ink, oil-based ink, blackening from hand grease over time, or brownish-red stains, and color transfer from clothing, and expose it to sunlight! It has no odor. ◇Store in a cool, dark place. A cool, dark place is a place where the temperature is low (around 15°C) and stable, with good ventilation and no direct sunlight. ＜Before Use＞ ●Wash the doll with a neutral detergent. ●Wear vinyl gloves to prevent the chemical from touching the skin. ●Do not allow the chemical to come into contact with metal. ●Do not use in places with temperatures of 50°C or higher, or near fire. ●There is a possibility that the doll's skin color or makeup may fade. Be sure to test it in an inconspicuous place and check for any abnormalities. If color fading or abnormalities are observed, do not use. ＜How to Use＞ ①Take the chemical with a cotton swab and apply it thinly and evenly on the stain. ②Place it in a safe outdoor location and expose it to sunlight. The exposure time varies depending on the amount of ultraviolet light contained in the sunlight. Adjust the time, aiming for 10 to 60 minutes depending on your region and the season. ③Wipe off the chemical with a soft cloth. Repeat steps ① to ③ until the effect is achieved. ＜Product Features＞ This product uses ultraviolet light contained in sunlight to react with the chemical components and decompose pigments to lighten stains. It takes longer to see results in environments with weak sunlight. Also, the chemical is less reactive in low-temperature environments, so it takes longer to see results.
