This is a darkening solution for silver products from Sea Force. I purchased it but won't be able to use it all, so I'm selling it. Would this be good for those who want to achieve a vintage or antique look and aging, or for those who have wanted to try it? ・What will be shipped: [Pure Black 10ml] [1 bonus cloth] I plan to remove this listing if there's no demand. It turns truly black, not a brownish-black like chlorine-based solutions. When applying, depending on the area and size, please use tools such as: Tweezers Small brushes Cotton swabs *Applying after thoroughly cleaning will result in a beautiful finish. As a bonus, I'm including a polishing cloth with a fine abrasive for silver products. I believe you can enjoy your silver products for a long time by applying a fluorine-based Silver Keep for tarnish prevention or Suffix for metal allergies. ※Regarding the item for sale: ・The container (bottle) may differ from the image. ・I plan to measure 10ml with a syringe and send it. If you would like additional cloths, I can add one for an extra 50 yen. Also, if you need cotton swabs or tweezers and don't have them, I can provide them for free. Please contact me before or after your purchase if you need them. I cannot add them after the item has been packed. Blackening liquid Silver black
