Nextorage CFexpress 4.0 Type A 512GB A2SE, brand new and unopened. Compatible with CFexpress 4.0, allowing for faster transfer speeds than standard CFexpress Type A cards. I purchased six for use with my SONY camera, but I no longer need four of them as I was able to get Lexar Gold cards at a lower price. I'm selling them for less than the retail price, so please purchase them if you need them. They will be wrapped in bubble wrap and shipped via Nekopos (a Japanese delivery service). I am also selling them on other flea market sites, so your order may be cancelled depending on the timing. (The price is slightly higher here due to the fees.)
