Hi and welcome,
Unless you can authenticate the devices, they are presumably clones of the originals.
Photos can help, but if they are clones, they may have a residual value of about $15 each depending on condition.
If the Nemesis had an 18650 battery installed, then it is missing a component called the "kick" tube and is NOT complete.
The
svoemesto is called a
kayfun.
Many models of the
kayfun have been released by the OEM and by Chinese clone manufacturers.
Many are virtually identical and difficult to authenticate.
You may offer them for sale here in the classified section, but it is suggest that you achieve 5 posts to activate Personal Messaging for communicating with prospective buyers.
Hope that helps.
Cheers
I
