Suntory Minami Alps no Tennensui

Both are animation masterpieces that just so happens to be ads 

Parched? Quench your thirst with these beautifully animated beverage commercials by Suntory and Lipton. 

A boy, a girl and their choice of drink—mineral water in Suntory Minami Alps no Tennensui and milk tea in 667-tsuu no Love Letter. 

You like the main movies? Then I don't see how you won't like the ads the two spring off too. Visuals are equally good looking, the sound is still incredible, it is just a matter of if the ads will be useful to you or not. 

You want something to drink? Just take Suntory. It is just good water I'd imagine, as good as the presentation here. From great visuals and sounds to stick to your mind for a very long time. 

Schick x Evangelion and Suntory Minami Alps are commercials using a very popular franchise to advertise products. Both are short. 

Great commercials there for *you* to know what to choose to drink. I mean, it looks good, sounds good, quite memorable I suppose. I'd say they are successful adverts. Honestly though, if Ghibli's name or CoMix's name doesn't get you into this ad, then I don't know what will. 

Both are short commercials paired with a popular anime. Sante FX eye drops with One Piece and Suntory mineral water with Kimi no Na wa.
