As you can see they are MDF tiles with cut outs for you to have you trees, or whatever, attached. Now I know these are not the first to do this but they do a wide ranges of different sizes and also plain tiles too.
It does also make packaging away and storing the trees earlier and if I want the trees to be separate I have them based already. Plus I can change the wood to include rocks, animals or any other thing that I might need like a base for cattle. I think these can prove to be a very useful indeed especially as they can is different sizes and the cut outs can be of differing sizes too.
I can recommend them and will be getting more of them shortly.
So have a great week ahead.
