Much too tall
I would not recommend this product for N-scale. I know that at 1 tall that equates to over 12' tall in scale so that is beyond usable in N-scale, but one solution I'm using is basically planting them deeper so that they are much shorter. Being there is only 40 per pack, you'd need a LOT of them to do a field. That would get costly pretty quickly. Having said all of this though, they are very nicely detailed. I would not recommend them for N-scale but I feel they'd be fine for HO.
