Looks like the same packaging mine came in when I ordered some from Kala back in the day.
I didn’t like them on the Kala Concert travel uke I bought them for, but they sound pretty nice on an old mahogany Kamaka Soprano I’ve decided to sell. My batch was dated 2017, iirc, but was purchased awhile ago so was likely current-ish when I got them.
They definitely don’t feel exactly the same as the Nylguts to my amateur feel, but I am pleased with their tone on a warmer uke. You might need to play around with finding the right uke for them, if that’s an option for you, but they are in my mind overall good strings. As always, ymmv.
