STL : The mysterious UK toy importer - who are they ?

STL : The mysterious UK toy importer - who are they ?
I recall a number of mysterious companies operating toy Importing (or general importing) business often out of London or Manchaster... one called Kingsley Paige (also known as United overseas Limited) springs to mind.
But the Voyager Generations that are around at the moment are labelled as coming from : STL The Lexicon 10-12 Mount Street Manchester M2 5NT.
The problem with that is that is actually a recycling centre's address.
or it comes up as Mazar's LLP (an accountancy company that shares directors with the STL) or even Starbucks has the same address.
So perhaps that is a tiny micro-office or a mail drop.
But there are employees listed for them on Linkdin and this suggests they exist possibly under the name Singleton Trading Limited.
Yet all you get from a search for them is the linkd in page and the company registration.
So in short - who the heck are they - why so mysterious ?
I was trying to track them so I can suggest to some retailers to stock their stuff but they seem almost invisible.
