The tray was a I’ll try it out purchase. I chose the color so I could see everything that I poured out of my grinder ready to use. I have not noticed anything sticking to it yet, but I just got it. The funnel in the corner is pretty useful too. Pour your grinding into a container or whatever. A brush would be nice to have included, but you can get a cheap one in the craft or discount shop. Overall it’s a good buy. Worth the price definitely.
