With Concrete you are armed. It's square, right angled, it does not move. Once poured and solidified, it's a sure bet. Go ahead and check out your favourite skyscraper. Or you can just put the grey concrete laces in your shopping cart.
You're wearing the colour of the Gherkin, the Shard, Heron tower, Fenchurch, Shell centre...You still want more? In my opinion, with the colour concrete grey in wide laces, it’s immobilized!
