These modified USB flash drives are built with 80s-era pentode radio tubes from the then-USSR. Their nifty repurposing should please steampunk fans, or anyone in search of a steampunk gift.
The vacuum tubes are made with real copper and, here, house SanDisk USB flash drives. Data storage options range from 8GB to 64GB, and the USB supports 1.0, 1.1, and 2.0, and is compatible with the 3.0 interface. Use your industrial drive with WinXP, Vista, Windows 7, 8, and 10, Mac OS, Linux, Android, and smart TVs.
