My Pengaree Assam I've ordered from Chaikhana
, a Swedish shop with English page and worldwide delivery. They also have Sessa Imperial Silver Tips
that I haven't tasted (yet!) Their Pengaree says 0,00 Swedish kronor as a price now, so something is wrong, but they say it's in stock.
My Joonktollee I buy from Stockholm Tea Centre
, another Swedish shop that delivers worldwide and have an English site.
I have a sample caddy of Mangalam Assam at home right now and look forward to trying it.
