No, Conjured objects are perfectly visible to people without nen.


 * Example - Kortopi's ability was still auctioned  and sold in York new to  people w/o nen abilities. Kurapika always have his chain conjured so Light Nostrade (also a non nen user) can see them when he was dowsing for Neon's location.

However conjured objects can be hidden from the senses by the advance nen technique "in" (conceal) since it's still made out of nen.

but I doubt that "in" can make it possible for conjured things to pass through doors/walls like a ghost while it's out in it's conjured form already. Unless it's been unconjured first then reconjured again maybe then, but that will release the hold on the target you ensnared.


 * Example - During Kurapika's fight w/ Uvogin, he tied down Uvo with the chain by hiding it with "in", the chain can still bump into things even if it's concealed with "in" they just won't know what hit them.  If he unconjure the chain for any reason it will release Uvo and he will have to reapply the chains again.
