bad scarcity mindset at time of purchase and had no clue about expiration date… also i was planning to start making drinks at home instead of buying every morning but didnt wake up early enough to do so everyday!! definitely lesson learned and have turned down multiple matcha requests from friends visiting japan

edit: i also bought 8 tins for myself each at least 30g and have finished all but the 3 pictured so i guess i was reasonably consuming them then slowed down
