OK, I got the older version of this laptop bag (7/16), mine doesn't come with those triangular flap click.
The case has 1 of those either side at the front of the laptop. Those don't hold it in place at all.
I have several bags like this bought from Amazon for £1 or £2 in lightning deals . Cold
What triangular flaps?
Not really. Those 2 triangular flaps at the front of the laptop don't even keep it in place when using it on a flat surface!
