The offer: verified structural compatibility
Precision tooling specs map every protective case, tempered glass shield, and small hardware component to exact smartphone chassis measurements. A case that fits loosely allows abrasive sand particles to grind against the phone frame. A case that is molded too tight strains corner antennas and causes screen glass protectors to bubble.
Every specification sheet in this matrix documents the three critical clearances: the display perimeter lip height, the camera plateau standoff ridge, and the USB-C plug opening width.
Confirmed price brackets by product class
Our inquiry catalog operates on three confirmed price brackets:
- Smartphone cases: 20–40 USD each. Hybrid dual-layer, ultra-slim polycarbonate, or liquid silicone shells with calibrated button actuators.
- Tempered glass shields: 40–60 USD each. 0.33 mm edge-curved aluminosilicate glass cut with 0.15 mm edge relief to prevent case lifting.
- Essential accessories: 15–30 USD each. CNC aluminium alloy camera guards, acoustic mesh speaker filters, and lanyard anchors.
Lead times are same-day for stocked models and 1 to 3 business days for commercial order batches.
Verification under Illinois commercial standards
Procurement operations are directed by Alina Koval since 2022. Every batch is inspected with Mitutoyo digital calipers at our Chicago facility (400 South LaSalle Street, Chicago, Illinois 60605). Shipments are documented with commercial supply invoices and physical fit sign-off sheets.

Why universal cutout cases fail modern camera systems
Many low-cost factories cut one oversized rectangular opening across the entire camera module. When a phone is dropped on gravel, this open aperture provides zero protection for the individual sapphire lenses.
OnlyCases protective cases feature individual raised collar bezels around each lens housing, maintaining a minimum 0.6 mm standoff when resting flat on rough surfaces.
Tactile button cover travel
Cases utilize independent CNC-machined aluminium button covers backed by silicone damping pads, providing 0.45 mm clean travel with zero squish or mushiness.
Heavy-duty USB-C port clearance
Cutouts measure 12.8 mm by 6.8 mm, accommodating large braided commercial charging cables, Thunderbolt docking connectors, and audio dongles without binding.
Acoustic port alignment
Speaker and microphone apertures align within 0.1 mm of the phone’s CNC chassis holes, preventing audio distortion or beamforming microphone muffling.
Screen protector edge perimeter gap
Our tempered screen protectors maintain an exact 0.35 mm to 0.50 mm perimeter margin from the display edge, allowing snug protective cases to snap on without lifting the glass.
