Flagged inconsistencies on the brand's own page
- The specifications table lists a '100g can' size with dimensions (diameter 7cm x height 10cm) and a 7-month best-before period, but no corresponding price or purchase option for a 100g can appears anywhere in the size/price selector at the top of the page (only 20g and 40g can are purchasable). This is a direct inconsistency between the specs table and the buyable SKU list.

Research notes
Tenju stands out as the only product in this batch with an explicit award/competition claim, an explicit harvest-method claim (hand-picked), and a distinctive packaging detail (tea name printed on box). It is also by far the most expensive product surveyed.
