Are these light fixtures conductive?

I came across this eshop http://www.jamjar.gr/store/edislamps
 
They sell decorative lights. The lamps they are using look like mains powered and the fixture is conductive and part of the live circuit, or am I mistaken?

If so, this is electrocution waiting to happen. I was going to send them a message, warning them about the dangers, but I'd like a second opinion first. I wouldn't want to alarm them for no reason.

Its almost certainly got a ceramic or phenolic insert between the body and the outer ES terminal.  However they appear to have two wire mains leads and exposed metal parts, and I would want to see their full CE declaration of conformity (under DIRECTIVE 2014/35/EU), with its technical report to satisfy myself that the socket had reinforced insulation and was fit for purpose without earthing.

Honestly I don't trust any lamp manufacturer anymore. They all write appliance class II / Schutzklasse II and CE on their shit, but often insulation and cabling is of piss poor quality, independent of (supposed) country of origin and brand name. It has a mains cord, it gets a new one and the case is PE'd. It is for permanent installing, the case is PE'd. End of discussion.

Re. the actual topic here, these look like the vintage brass E27 sockets still sometimes found in cellars around here. The outer brass shell isn't connected to anything or PE, there is an inner threading insulated by a bakelite or ceramic insert. I don't think they're "finger-safe" though. So maybe nothing to let little kids play with. It could also be the case that these lamps are actually low voltage lamps and the lamp base contains a transformer.
