OIIAEE Liquid Silicone Case for iPhone 13 Pro Max (6.7 inch) – Ultra-slim shockproof cover in Stone
Product description
If you’re after a protective iPhone 13 Pro Max case that doesn’t feel bulky in your hand, this OIIAEE liquid silicone case is aimed at exactly that. It’s designed around a soft, skin-like surface, with shock protection and a microfiber lining to help reduce the tiny scuffs that can build up over time.
That said, “ultra slim” is always a balancing act: you’ll get a sleek profile, but it’s not the kind of case that’s trying to be a tank. It’s more about everyday drop and scratch resistance than extreme impact testing.
The essentials
This OIIAEE case is made from liquid silicone and is built for the iPhone 13 Pro Max (listed as 6.7 inch). The outer finish is described as smooth to the touch, with anti-scratch and anti-fingerprint claims, plus cut-outs positioned for buttons and ports.
On the inside, there’s a soft microfiber lining. The idea is simple: the case “hugs” the phone around the edges to reduce movement and abrasion where it could otherwise rub.

Outside, the raised lips matter in day-to-day use. The listing states a 1.5 mm raised lip for the camera and a 1.7 mm raised screen edges, intended to help protect the most vulnerable areas when your phone is placed face-down or on a rough surface.
Key features that affect daily use
The most noticeable difference with a silicone cover like this is grip and handling. The surface is positioned as smooth and not overly slippery, while also being resistant to fingerprints. In normal life—slipping your phone into a pocket, picking it up one-handed, using it on the sofa—this is the kind of case that tends to feel comfortable rather than sticky.
Protection is approached in layers. The flexible silicone shell is meant to take the sting out of minor knocks, and the microfiber lining is there to minimise micro-abrasions.


Also worth calling out: the listing says stains wipe off easily with a damp rag. That’s helpful if you’re the type who gets sleeve marks, dust, or general grime on phone cases.

What to consider before buying
It’s designed to be “ultra slim”, and that can be a limiting factor if you regularly deal with hard falls, rough environments, or you like thick, blocky protection. Raised lips help with surface contact, but this is still a slim silicone case rather than a multi-layer impact shell.
Another practical thing to note: silicone cases can be great for comfort, but they may show wear differently than rigid cases. If you want something that stays looking pristine for years regardless of usage, you might find silicone requires a bit more care and regular cleaning.
Finally, the colour option here is Stone. The listing says multiple colours are available, but if you’re choosing based on how the colour ages, it’s smart to consider that silicone finishes can darken or pick up marks over time.

For what kind of user it makes sense
It’s a solid pick if you want a comfortable, slim iPhone 13 Pro Max case with basic shock and scratch protection for everyday carry—commutes, desk days, school runs, and those “oops” moments when your phone catches a corner.


It also makes sense if you prefer cleaning to be straightforward. Wiping with a damp rag is usually a quick fix when you notice smudges.
On the flip side, it may not suit you if you routinely drop your phone from height, work in a particularly harsh environment, or you’re expecting this to replace a heavy-duty protective case.

Getting the most from it
A quick, realistic use example: imagine placing your phone face-down on a coffee table. With the raised screen edges mentioned in the listing, the goal is that the glass stays slightly lifted rather than taking full contact with the surface. Then, when you lift it again, the silicone texture should help you grip it securely without fishing for traction.
To keep it looking good, wipe the case occasionally with a damp cloth. Don’t overdo it—just enough to remove everyday grime—then let it dry.
Is it worth it?
This OIIAEE liquid silicone case is worth considering if you like a slim feel, want comfort in the hand, and appreciate the combination of raised lips plus a microfiber lining for everyday protection. It suits buyers who want practical, everyday coverage rather than extreme bulk.

You may want to skip it if you’re hard on your phone and need heavier, more impact-focused protection, or if you’re looking for a case that’s unlikely to show any wear at all over time.
If your top priority is wireless charging, the listing also states it’s 100% compatible, so it should work with that setup without you having to remove the cover.
