This is something about Amazon - you can find almost anything you can think of there. These molds I am intending to use for a small patio project. They are constructed of a very sturdy plastic and a unique pattern. I hope to mix the cement mix with a powder dye which will add to the overall effect. Admittedly with four molds, this is going to be a slow project, as I need about 400 tiles - that's 100 times making up four molds. Would have been useful to have different quantities of molds offered.

I love the way my bricks are coming out, I added black cement dye to them so I could get a dark grey brick

Will hold up to thousands of pavers. Lightly oil them fill with cement vibrate or tap/ bounce and pop them out next day. The more vibration means a smoother surface. No air bubbles.

All four molds had gouges in them in the exact same location. I returned these as I don't want to spend money & time creating steps that are flawed from the get-go.
