you are very lucky to find loose leaf tea.....recently i noticed how difficult it is to get Lipton loose leaf ( or t bag) a million coffee products but alas Thais do not understand tea - thai tea is a milky affair. Only product is dimar tea which is not very good but better than nothing .Nowadays you have to buy it online - no point going to the local supermarkets or 7/11,big c , makro,lotus. Tea the most popular drink in UK. barely given a second look by the stockists of thai stores ..yet Vietnam is awash with the stuff mostly green tea.Lastly one is required to stir one's tea in the same direction as the earth spins, for a truly perfect cuppa
