I can see they took inspiration and designs from existing harry potter film ones. the Holly and Birch handle are taken from fred or george's wands and the wand called the Vine has the handle design of Umbridge's. The Elder though is a wand design which is based from the unknown deatheater wand and is a wand Noble is yet to produce (hopefully)
Another thing that bugs me is that the wands are still made of resin. I can see that there is an expense and easy production en masse, but resin, like the Noble wands is very fragile!:cryYou
do know that those wands are for display, right? You're not supposed to actually
use them.
I don't see why they could not have taken advantage of a wand producing place such as Alivans - some are reasonably affordable!
