This is a set of 3 used Baby Mag-chan laundry aids. They have been used, but the total weight of the three is 238g, so I think they can still be used. Please understand that these are used items, and I would appreciate it if you could use them as a trial or for fertilizer. ★Product Details Product Name: Laundry Aid Application: For cotton, linen, and synthetic fibers Acidity: Weakly alkaline Material: Outer bag: Polyester/Nylon Inner bag: Polyester Ingredients: High-purity magnesium Country of Origin: Japan Thank you for looking.
