Review on SYHL Invisible Magnetic Closure Fastener by Gelin Battle

Would like more information on the product and its use. So I did my own testing to make sure this product could be used the way I wanted it to, ie replace a button down shirt with magnetic closures as an adaptive modification for a person with tremors. The magnets are machine washable and dryable, with or without a plastic coating. I soaked them in fresh water for a week with no sign of plating leaks or rusting on the magnet I tested outside of the case. Also, I put the iron on the magnet included in the case at maximum power for 15 seconds and the case didn't melt. However, I would re-test on a case-by-case basis for other types of clothing.
