YOSH 3M Sticker Metal Plates Replacement Mount (Pack of 4) – Round Black 0.4mm
Product description
If your magnetic car phone holder is working but the backing plate has started to lift, these YOSH 3M Sticker Metal Plates are the sort of replacement you buy once and then forget about. They’re designed to add a thin, metal mounting surface for magnetic cradles, without the plate itself being magnetic.
On paper, the idea is straightforward: stick the metal plate to your phone or case, and your existing magnetic holder can clamp on as normal. The details matter though—adhesive choice, thickness, and how scratch protection is handled.
What this is for (and what it isn’t)
This is a kit of round metal plates used with magnetic car phone holder magnet cradles. The plate is simply a metal sheet accessory, it doesn’t provide magnetism on its own. Instead, it helps most compatible magnetic holders “grip” to a metal surface.
A key limitation to know early: the plates can interfere with wireless charging. If you rely on Qi charging, you’ll need to stick the plate onto a phone case (and remove it before wireless charging if required), rather than expecting it to be invisible under the handset.
The essentials: adhesion, thickness and day-to-day feel
The standout element here is the adhesive backing. These YOSH plates use authorised 3M glue on the rear, which is meant to keep the phone stable while driving. The aim is a secure bond that doesn’t peel off easily and avoids leaving sticky residue behind when you remove the plate.
Thickness is also a big part of the comfort story. At just 0.4mm, it’s thinner than many alternatives in this space. That kind of slim profile can be the difference between a case feeling slightly “lumpy” versus largely normal when you slide it into your pocket or hold it on the move.
You also get scratch-resistance support: protective films are packed inside. The suggestion is to apply the protective film on your phone or case first, then add the metal plate on top. It’s a small step, but if you’ve ever had metal accessories mark surfaces, you’ll understand why they’ve included this.
Compatibility: where it should work, and where to be careful
The listing positions these as widely compatible. The plates are said to work not only with YOSH magnet holders, but also “almost all similar” magnetic phone holder setups.
That said, “almost all” is where you should be a bit cautious. Compatibility depends on your holder design and how it expects the mounting surface to be shaped and positioned. If you’ve got a very specific holder mechanism or placement, it’s worth checking whether it needs a particular plate location on the case/phone.
Also, because these plates are metal accessories, they’re not meant to replace MagSafe-style accessories that rely on their own magnetic ring alignment. If you’re specifically trying to solve for MagSafe compatibility, this isn’t described that way.
What you’ll notice in use
After installing, the practical difference is that your phone feels more “locked in” to the cradle. With a good adhesive bond, there’s less worry about the phone shifting during braking or uneven roads.
Micro example: imagine you’ve got a magnetic car vent or dash mount. You place the protective film on the back of your case, press the 0.4mm metal plate in place, and then mount the phone. From that point on, your everyday routine becomes simple—no fiddling with straps or mounts, just click-in and go.
Pros and cons to weigh up
Strengths
- 3M glue backing for a secure hold (and less worry about lifting)
- Very thin 0.4mm metal plate profile
- Protective films included to reduce scratch risk
- Pack of 4 means you can cover replacements or multiple cases
Where it may disappoint
- Wireless charging is the big one: the listing advises that the plate would interfere, so it may not suit if you want to leave it on the phone for Qi charging
- You still need to apply the protective film and plate carefully—if you place it badly, you may have a hard time enjoying it
- It’s a “replacement mount” accessory, so you’re not getting a full phone holder—if your cradle is the problem, this won’t fix that
¿Merece la pena?
A solid pick if you already have a compatible magnetic car phone holder and you just want a reliable way to keep the metal mounting surface fresh—especially if the original plate has started to loosen or you want spares for different cases.
It may not be the best choice if you primarily use wireless charging as your everyday habit. In that scenario, the extra step of removing it before charging (or avoiding placing it on the handset where charging is expected) can become annoying.
Buying decision: when to buy, when to avoid
It’s a good fit if you want a thin metal plate replacement for a magnetic car phone holder, you’re happy applying adhesive carefully, and you don’t mind thinking about wireless charging.
Better avoided if wireless charging is non-negotiable, or if you’re looking for a MagSafe-style accessory (this is not presented that way).

Care tips
When attaching, take your time with positioning and prep. The listing advises using the included protective film first—this is the part that helps reduce scratches. After fitting, keep the area clean and dry so the adhesive can bond properly.
Mini FAQ
Will the metal plate work without magnetism?
Yes. The plate itself has no magnetism, it’s the metal surface the magnetic holder clamps onto.
Can I use it for wireless charging?
Not as a straightforward “leave it on and charge” solution. The listing notes it will interfere with wireless charging, so you may need to use it on a case and remove it before using a wireless charger.
Does it leave residue when removed?
The listing claims it won’t come off easily and that it leaves no sticky residual after detaching.
What’s included in the pack?
A pack of 4 round black metal plates, plus scratch-resistant protective films.
Where should I stick the plate?
The listing suggests sticking the plate on the phone case (especially if wireless charging matters), and applying the protective film first before placing the metal plate.
