Green tea lovers, what’s your ideal birthday gift? Help!!

Hii!! ♡ My dad’s birthday is coming up and I NEED to buy him the best tea gift!!! I HAVE NO BUDGET!!!

TW: He only ever buys his tea from David’s Tea and that’s subpar according to this sub. He lovesss green tea like it’s oxygen. Has ‘Japanese Sencha’ every day

MY IDEA: I’m thinking of getting him one of every top-rated green tea! I’ve been watching YouTube videos and documentaries on the types of green tea, so I know it’ll be a lot of variety for him to choose from ♡

Any other suggestions for gifts are very welcome! I’m still new to the tea world and don’t know what else I could get :p I do know he tries ‘Nepal white tea’ sometimes! For now, I’m trying to find a reliable Japanese tea brand that sells all sorts!

PS. I’ve got absolutely no idea where to buy all of this so, I’d really appreciate it if you told me your fav green tea & where you buy it?

Thank you in advance!!💘
