iPhone 18 Pro Max Screen Protectors Compared: 100-Yen Shop vs ¥1,299 Amazon vs BELLEMOND Monster Film

This is the English edition of a review from my Japanese YouTube channel, iestaLife. I review gadgets from my home studio in Japan, so product links go to Amazon Japan.

Disclosure: BELLEMOND provided the Monster Film for this review. The other two films I bought myself.

Quick take

How much should you spend on a glass screen protector for the iPhone 18 Pro Max? I put three on the same phone: a 100-yen shop film, a ¥1,299 film from Amazon, and BELLEMOND’s Monster Film (clear). The cheap ones protect the screen, but the Monster Film was clearly the nicest to live with: it covers more of the display, leaves a smaller gap to the case, and its alignment kit makes it very hard to apply crooked. Its regular price was ¥1,698 at the time of recording for a two-pack with the kit.

The three films I compared

What I tested

  • A glass film from a 100-yen shop (Japan’s equivalent of a dollar store)
  • An EvoSpace glass film that cost ¥1,299 on Amazon
  • BELLEMOND Monster Film, clear type with a black border, for iPhone 18 Pro / 18 Pro Max: two films plus an applicator kit, ¥1,698 regular price at the time of recording
  • All applied to an iPhone 18 Pro Max and compared for size, ease of application, the gap to the case, Face ID and how the edges feel

What I found

  • 100-yen film: for the price, it does the basic job of protecting the screen. But it is noticeably smaller than the display. With a case on, the film stopped roughly 1 mm short of the case. You can feel the film’s edge when you swipe near the edge of the screen, and dust collects in that gap. Fine for a short time, but on something you touch all day, the small difference starts to bother you.
  • ¥1,299 Amazon film: at about ten times the price, I expected a big step up. In practice, its size and feel were very close to the 100-yen film. That doesn’t mean they are identical products, but I didn’t see a difference that matched the price gap.
  • Monster Film application: this is where it stood out. You set the iPhone in the applicator, line it up, and pull out a tab. There is almost no fiddling with “is this straight?”, so it is much harder to end up crooked, off-centre, or with dust from re-applying.

  • Coverage: the black-bordered Monster Film covers much more of the display than the 100-yen film, and the big gap to the case mostly disappeared, so the edges don’t feel stepped when you swipe.
  • Case compatibility: a film that is too large can be pushed up by the case edge; too small leaves a gap. With the case I used, there was no noticeable interference.
  • Face ID and display: Face ID worked fine after applying it, and I didn’t notice anything odd about the screen in everyday use.
  • Not a 3D edge film: this clear type doesn’t wrap right to the very edge like a 3D-edge protector. If you want edge-to-edge coverage, look at 3D-edge types. If you always use a case, avoiding case interference matters more, and I found this size well balanced.

Who it’s for

The Monster Film suits you if you are bad at applying screen protectors, want wider coverage and a smaller gap to your case, like a black-bordered look, and want a two-pack at a low price. The 100-yen film isn’t a bad choice either: I use one myself as temporary protection right after buying a new iPhone, while I wait for a proper film to arrive. The question is whether you can live with its size and edge feel over the long term. BELLEMOND is a Japanese brand, so it may be harder to find outside Japan.

Limitations

This compares three specific films on one iPhone 18 Pro Max with one case; other cheap films on Amazon may be better or worse. If price is all that matters, the 100-yen film is by far the cheapest. The Monster Film was provided by the brand. Prices are what I saw in Japan at the time of recording.
