This topic is for those who sometimes wonder, is this brick actual LEGO? If you have ever asked yourself any of the questions listed below, you may want to read the topic.
Do I mix my similar brands together?
Do I have bricks without LEGO on the studs? (Plates do not apply)
Do I have any figs that clearly aren't LEGO? http://vignette1.wikia.nocookie.net/megablokshalowars/images/c/cf/Megabloks-forward-unto-dawn-97117-3086.jpg/revision/latest?cb=20121203202408
Have you ever bought custom pieces?
I will help with these problems. If you post(with an image) I will read it.
