25-key USB MIDI keyboard, compact and convenient for portability. Thank you for viewing. I purchased this around August of last year, but I've only used it once. Please note that there is no outer box or instruction manual, only the included USB cable. Regarding usage, I confirmed its operation by connecting it to Logic Pro, a DAW for Mac, and it worked without any problems. When shipping, I will wrap it in packing materials and ship it as safely as possible. - Model Name: MICROLAB - Brand: ARTURIA - Connection Type: USB - Number of Keys: 25 keys - Included Items: USB cable
