TL;DR:
MagSleem is magnetic and removes in seconds, perfect for maintenance and quick plate swaps when needed. SuperSleem is cheaper yet just as stable on the car, and it sits almost flush with the bumper at about 3 mm, versus MagSleem’s 18 mm plate-to-bumper distance. Both systems use premium, ultra-resistant plastic, are screw-mounted, no adhesives, aligned with law when installed correctly, and require no maintenance.

Who MagSleem is for

  • Clip on, clip off in seconds
    Magnet–magnet system with 2 lateral contact points per plate, 4 magnets per plate in total. The combined attraction force is tuned for daily driving, high speeds, rough roads and temperature swings.
    Neodymium N52 magnets, zinc plated with a black epoxy anti-corrosion finish for a distinct premium look. Magnet size Ø20 mm, thickness 5 mm in the holder and 4 mm in the puck.
    The plate sits about 18 mm from the bumper, creating a controlled clearance and a floating aesthetic.

  • Photo, video, events, detailing
    If you shoot content, attend shows or want to alternate between custom and road-legal plates, MagSleem lets you remove or swap instantly. It is handy for detailing when you want full access behind the plate.

  • Easy upkeep
    At the wash, keep the pressure wand 30–40 cm away and at an oblique angle. Recommended operating window is −30 °C to +60 °C. No maintenance needed, optional winter rinse.

  • Compatibility
    Our primary target is the EU 520×110 mm plate. MagSleem X supports plate sizes worldwide. Bumper material does not affect retention because the system is magnet–magnet via screws. In real-world use we have not observed issues with parking sensors, ACC, radar or cameras.

  • When MagSleem shines
    Photo work and social, rapid plate swaps, fast access behind the plate, cold-season cleanup, wrap or PPF projects where you prefer some standoff, product presentations and reviews.

Who SuperSleem is for

  • Ultra-slim, OEM-like look
    Plate-to-bumper distance of about 3 mm. Clean, nearly factory-integrated appearance. This is the go-to when you want the plate as close to the bumper as possible.

  • Lower price, equal stability
    SuperSleem is more affordable while staying stable for daily use. It contains no magnets at all. Screw-mounted, no adhesives, durable plastic.

  • Aerodynamics and quietness
    The almost flush profile reduces frontal gap and can minimize specific wind noises depending on bumper geometry. In everyday driving the difference versus MagSleem is subtle, but many owners like the tidy, fixed-in-place look.

  • When SuperSleem shines
    Daily driver, discreet visuals, budget focus, you rarely remove the plate, you want a set-and-forget mount.

Key differences at a glance

    MagSleem: magnetic, 4 magnets per plate, instant clip on/off.
    SuperSleem: slim mechanical mount, zero magnets, not designed for frequent removal.

  • Plate-to-bumper gap
    MagSleem: ~18 mm.
    SuperSleem: ~3 mm.

  • Upkeep
    MagSleem: remove, clean, reattach, very easy.
    SuperSleem: clean in place, minimal intervention.

  • Price
    SuperSleem is generally less expensive. MagSleem brings premium convenience through quick removal.

  • Use cases
    MagSleem: content, events, detailing, fast swaps.
    SuperSleem: low-profile, leave-it-on, OEM-like fit.

Good-to-know before you buy

Is it legal?
Yes when installed correctly. Romania’s HG 1391/2006 requires plates to be placed in the manufacturer-designated front and rear locations and to remain visible. The mounting method is not explicitly specified. Keep the plate readable and in the intended positions.

What plate size do you support?
We target the EU 520×110 mm standard, and MagSleem X supports other world sizes.

Car wash and weather
Follow the 30–40 cm, oblique-angle rule. Recommended operation −30 °C to +60 °C. Real-world use includes rough roads, motorway speeds and winter conditions. No lab certificate, but extensive field validation including off-road and track driving.

Sensors and radar
We have not observed interference in real use. Attachment is via screws, with the magnet–magnet pairing localized at the holder, separate from bumper materials.

Warranty and returns
EU buyers benefit from a 2-year legal guarantee and a 14-day right of withdrawal for distance purchases. We also offer a 90-day satisfaction return if the product is intact. 

Anti-theft
No dedicated anti-theft option yet. Use common-sense precautions. With MagSleem you can simply remove the plate when leaving the car at shows or in sensitive areas.

Subtle advantages

  • Finish protection
    On PPF or wraps, MagSleem’s 18 mm standoff can help avoid rubbing. SuperSleem’s 3 mm nearly-flush profile is visually perfect; as with any slim mount, check early for micro-marks on very soft films.

  • Access behind the plate
    MagSleem grants quick access to grilles or sensors for cleaning. SuperSleem stays put, which many owners prefer for a quiet, consistent look.

  • Visual balance
    The floating look of MagSleem highlights sculpted bumpers; SuperSleem preserves factory lines.

  • No adhesives in the kit
    All current kits use screws, with IPA wipes included for surface prep.
