Normally, I would discourage giving tea, but a complex Mariage Frères
infusion is much more special than your garden variety Chamomile or Earl Grey. It's also pretty hard to find stateside (the company, founded in 1854 in Paris, only has storefronts in France, Great Britain, Germany and Japan), so having a tin in the cupboard feels like entrée
into an exclusive club. Just remember to include filters, since the leaves are often sold loose!
