What strings come on a Leho?

So I recently picked up an arch-back ebony concert ukulele from Leho. It is a sweet little instrument for the price!

What I'm wondering is what sort of strings come on it from the factory. Odds are decent that they're "Aquila new nylgut" from all I've heard, but I'd like to know for sure so I can help choose where to go when I wear these out.

I've asked on their facebook page, but no answer so far.
