This is a set of adapters that allows you to use multiple microSD cards as SD cards. All items are unused. Since they are unused, I have not tested their functionality. Please be aware of this. If you purchase a single adapter, it will be 500 yen, and two will be 888 yen. If you would like to purchase four, you can buy them directly at this price. - Type: microSD to SD Adapter - Brand: Transcend - Brand: Gigastone - Brand: SP - Type: microSD to SD Adapter Thank you for looking.
