Slim Case (TPU) with Hand Strap? Dummy Cover? Or Alternative Case?

[Culverin]

Hi,

I wanted a case with a hand-strap and narrow kickstand.

Originally, I got one with silicone instead of TPU body. However it turns out it is far too bulky.

So instead, I picked up one of these from AliExpress.

The case is actually quite a good fit, however, at the bottom of the case, there looks like there is about 1/4" intended to fit the OEM keyboard.

You can see that 1/4" quite clearly from the 5th photo.

The thing is, I don't need a keyboard. I just want something to cover the screen when it goes back into my backpack.

Just wondering if there's a dummy keyboard I can remove and peel away for when I'm working,
Because I want to use the tablet as a monitor quite close to my mouse hand.

Alternatively, can you suggest me a TPU case with a hand strap similar to the Amazon link above?

Thank you so much!!!
