I purchased 1200g of high-purity magnesium several years ago as laundry balls. I used some of it once or twice, and the rest has been stored unused. 《See images below》 ・Unused: The surface has slightly darkened due to aging and oxidation, but there is no problem with use. (It is recommended to soak it in citric acid or vinegar) ・Used: Slightly whitish, but still usable. ・The package label is a little dirty. - Brand: Mag Choice - Ingredients: High-purity magnesium 99.95% - Size: 6mm - Weight: Unused approximately 900g (921g including the transparent package) + bonus approximately 300g (used 1-2 times. Will be placed in a separate bag without mixing) - Please let me know if you do not need the bonus. However, please note that the price will not change. I will send it via Takkyubin (Compact). Thank you.
