LEGO Iridescent Blue & Chrome Black Key Chains!

I made an accidental discovery a couple of weeks ago when I placed an order from the Online LEGO Shop. LEGO has two new very unique and unusually beautiful keychains. The #853993 LEGO Iconic 2×4 Bright Blue Key Chain features an iridescent 2×4 LEGO brick that shimmers when viewed from different angles, and the #853992 LEGO Iconic 2×4 Black Metallicized Key Chain features a 2×4 LEGO brick with a metallic shine. Because LEGO included some really bad pictures with both of these key chains at the Online LEGO Shop, it is very easy to overlook them, so below, I will show you their real beauty.

Here are the images LEGO is using for these key chains at the Online LEGO Shop. As you can see, they just look like regular blue and black 2×4 bricks. It’s only in the description of the key chains is where you notice that they have unusual characteristics.

The #853993 LEGO Iconic 2×4 Bright Blue Key Chain has a very similar look to Sweet Mayhem’s holographic hair, so I photographed them together. Both pieces have an iridescent coating that makes them shimmer and glow when hit by light. The difference is that while Sweet Mayhem’s hair is bright-light-blue under the holographic coating, the 2×2 brick has a medium-blue base color. To make this more confusing, LEGO calls BrickLink’s medium-blue bright-light-blue, and BrickLink’s bright-light-blue is light-royal-blue for LEGO. The bottom line is that Sweet Mayhem’s hair is a lighter shade of blue than the 2×4 brick.

When you look at the #853993 LEGO Iconic 2×4 Bright Blue Key Chain in low light conditions, it looks like a 2×4 medium-blue brick with a slight shimmer. You can see this on some of the images I included. But when the brick is hit by a light-source it has an intense and bright glow, similar to holographic images. The glow is especially strong on top of the brick around the studs, but the iridescent coating is also applied to the sides, so there is some glowing effect there too. The underside of the brick is regular medium-blue with no glowing effect.

The #853992 LEGO Iconic 2×4 Black Metallicized Key Chain is less spectacular, but still very beautiful. It’s hard to capture such a dark and shiny piece on pictures, but it has the same black metallic chrome finish that LEGO previously used in the #4547551 LEGO Chrome Darth Vader promotional polybag from 2009. So, we could consider this a 2×4 Darth Brick keychain, or Darth Vader in disguise! The top and sides of the brick are coated with the chrome finish, but not the underside, which is just plain black.

Just like all LEGO key chain bricks, both of these special key chains are attached to a durable metal ring and chain, so you could definitely use them to keep your keys safe, or fasten them to bags. Keep in mind that if you do use these as actual keychains, the iridescent and chrome finish will eventually wear off. I personally will just keep them with my LEGO color collection as some of the coolest LEGO 2×4 bricks.

I love both key chains, and I’m super happy that I got them. If you are interested to check the #853993 LEGO Iconic 2×4 Bright Blue Key Chain and the #853992 LEGO Iconic 2×4 Black Metallicized Key Chain, they are available at the key chains section of the Online LEGO Shop.

What do you think? How do you like these special 2×4 key chains? Are you planning to get some, or do you have them already? Feel free to share and discuss in the comment section below!

    What???! This is the first time I have seen this!

  • Garmadon the Great March 19, 2020, 10:57 AM

    OMG! I didn’t know I needed this until now! Just wow!!!!

  • quinton March 19, 2020, 11:10 AM

    WOW!!! That holographic one looks amazing! Did they ever do anything like this before?

    • Thita (admin) March 19, 2020, 4:25 PM

      My understanding is that the first holographic piece was Sweet Mayhem’s hair. Chroming they have done several times, but black chrome is only for Darth Vader and this 2×4 brick. 🙂

  • TomTom March 19, 2020, 11:19 AM

    Holy holographic brick! Why is nobody else talking about this? Gorgeous!

  • BigShawn March 19, 2020, 11:25 AM

    I was just wondering what else to add to my cart! I’m surprized they didn’t post better pictures. They are missing out on so many sales!

  • gid617 March 19, 2020, 11:45 AM

    These look really nice but they sure are some expensive 2×4 bricks. 😛 I will keep my eye on the black chrome one though, in case it goes on sale…

    • Thita (admin) March 19, 2020, 4:26 PM

      It could very well go on sale because the picture in the description is so bad. Unless a lot of people read this article, and they make a run on the bricks. 🙄

  • legofan March 19, 2020, 11:46 AM

    Okay, I’m sold I want both. I wanted to collect 2×4 bricks anyway.

  • FrenchToast March 19, 2020, 11:50 AM

    I’m definitely getting the iridescent one. And I won’t be using it as a key chain to make sure it doesn’t get scratched up. Very nice find, and thanks for sharing. I would have surely overlooked those stock photos!

  • Martin March 19, 2020, 11:53 AM

    They should make more unique pieces like this. Collectors would be all over them. 2×4 bricks, weapons, and armor are some pieces that I know I would pay premium price for.

    • The Other Mark March 19, 2020, 11:55 AM

      Ha! I would take a holographic armor! Some chromed weapons would be nice too! They could sell special packs with unique colors like these. It doesn’t have to be just keychains.

    • Thita (admin) March 19, 2020, 4:26 PM

      I would love to see that! 😀

    • Håkan March 21, 2020, 8:08 AM

      Oh yeah. Sci-fi weapons and armor would be sweet…

  • Henry March 19, 2020, 11:57 AM

    How easy (or hard) is it to remove the pin? Does it just screw out? Or do I have to cut it?

    • Thita (admin) March 19, 2020, 4:30 PM

      It’s a long pin that goes about half way through the brick. It isn’t particularly easy to remove. You could use a soldering rod to remove it, but if you have never used this method before, I wouldn’t recommend it as you could melt the brick too much. If you want to remove the pin, I would recommend just to cut it right at the surface. That would be the least likely damaging method.

  • j.j. March 19, 2020, 1:30 PM

    These are very pretty! I think they also have some other new colors, like the pearly jewels in the Dots sets.

    • Thita (admin) March 19, 2020, 4:32 PM

      Yes! The DOTS bracelets have them. They have a pearl-like coating.

  • Ian March 19, 2020, 3:42 PM

    These are rad! I have already added them to my wishlist for the next time I shop. I hope they don’t run out of them because of this article. LOL! What a hidden treasure!

  • Paul Symons March 19, 2020, 6:18 PM

    Now I can add 2 more 2×4’s to my colour palette… Thanks!

  • Håkan March 20, 2020, 6:22 AM

    Cute, although they still might be hard to implement in a build…
