We recently came across a batch of these teapots & after confirming their authenticity, immediately bought them all. They're really very well made and come in original boxes (though some boxes have a little water damage)
The pots themselves are very well made and use good quality Zini. They're medium/high fired & very nice to use. Inside is a single hole filter. For those seeking a good quality Factory1 Zini pot from this period, these are a great choice.
