Question about Lenovo Tab M10 Plus Gen 3

Unfortunately, the tablet comes without the case. But we offer the official Lenovo one:
Lenovo Folio (Tab M10 Plus Gen 3, Tab M10 Plus)

Good morning, Sir,

I received the tablet today.

The pack includes:
The tablet
The case
The Pen

Best regards
Thierry

Yes, case and pen

What's the difference with the Lenovo Tab M10 Plus Gen 3, also sold here with double the memory?
