A Chinese company has created a one-of-a-kind cell phone.
It's called the "Flexpai."
Royole released it in Beijing on Halloween.
The Flexpai transforms from a tablet to a smart phone by simply folding in half like a book.
You can preorder the phone on Royole's website.
It costs about $1,300.
However, tech journalists who tested the phone say it's processor is slow and it's bulky.
