Product Description

Each of these bricks is precision CNC machined from aircraft-grade aluminum. One end has a drilled and threaded hole which accepts a small eyebolt (included) to turn this shiny brick into a keychain. These are the exact same size as and fit together with LEGO® brand bricks, but they'll last much longer in your pocket or banging around with your keys.

See our personalization options to turn this into a one-of-a-kind gift or memento.

    I first saw these bricks featured on the www.brothers-brick.com blog in July '08. I bought a couple for my friends (and for myself too). Postage and service was very efficient and speedy. They're light and shiny - a must have for "The Brick" enthusiast.

    I ordered my keychains based on reviews I'd heard from friends who had purchased some. I was mainly buying these as a gift for my wife, who has collected keychains for years, and has several official Lego minifig keychains in her collection from me already. So this time I was hoping to make it more special. The engravings I decided to go with were the boy and girl minifig heads with a heart between them, and our anniversary date on the back. When I gave my wife her's, she really loved it, and instead of putting it on her keychain racks where the rest always go, she actually put it on her keys. I can't come up with a better testimonial than that.
