This is a new Bytech Large Universal Smartphone holster.  The phone beside it is an iPhone XS (and, of course, is shown as an example and is not included -  - sad that I have to put this disclaimer in here).  Approximate inside dimensions of case are 5.5 x 3 x 3/4".  It has the swivel holster clip and the Velcro Closure Latch and elastic adjustment on the sides.

For iPhone 6, 7, SE (2nd) the case will also accept the phone with a slim or rugged protective case.  For the others a slim case only (though if you want to use a rugged protective case on those phones you could upsize to the extra large found at this listing  274945282298 ). 

Thanks for you interest.
