I built some of these for a friend's HO layout. With some extra effort like painting the trunks and replacing the little circular base with a pin, you can have a decent tree for a nominal price. I recommend using Goop for the adhesive and applying the clump foliage one branch at a time. With foliage applied, the shortest trees in the package are about an inch tall. That's 13 feet in N scale, so I would not recommend it for that scale. Otherwise it can be a good buy if you're willing to go the extra mile.
