Chicago catalog operations verify hardware compatibility
OnlyCases is an inquiry-only physical catalog resource based at 400 South LaSalle Street in Chicago, Illinois. We supply protective phone cases, precision back covers, 9H tempered glass screen shields, and MagSafe accessories for corporate fleets and trade buyers.
Physical catalog desk, not a consumer checkout cart
Inquiry-only desk workflows guide every catalog transaction. We do not provide an instant cart, an online payment terminal, or generic automated dropshipping. Every customer request is routed through our Chicago desk for physical verification against target device specifications.
Our operations are registered in the State of Illinois. Commercial buyers receive detailed supplier commercial invoices and certified batch specification sheets before any physical shipment is dispatched from our inventory.
Precision component inspection and batch procurement
We inspect polymer formulation, Shore A durometer hardness, bezel ridge clearances, and optical glass flatness across every commercial batch.
Procurement management by Alina Koval since 2022
Alina Koval oversees direct factory procurement, batch sampling, and physical dimensional inspection. When a smartphone manufacturer updates a camera bump extrusion from 2.1 mm to 2.4 mm, our tooling CAD models are revised immediately so that our protective perimeter ridges clear flat surfaces by at least 0.5 mm.
We decline to carry cheap unbranded regrind plastics or brittle soda-lime glass protectors. Our catalog limits its items to verified thermoplastic polyurethane, Bayer UV-stabilised polycarbonates, aluminosilicate tempered glass, and liquid silicone rubber.
