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.
