Sketchbooks, you can never have enough and people will always use it. Like, I'm not going to slap some other company's sticker on my water bottle/laptop/etc.

Pens & totes are cool too.

I've really been digging those bagu reusable bags lately — in SF, where plastic bags are outlawed, they come in WAY handy.

Branded stickies & sharpies

Sketchbooks are the shit. Stickers are cool, too, but they need to be cool. Logo stickers just don't get used, unless they're from an already loved brand.

Fridge magnets. No one ever throws those away. You're just buying cheap ad space on someone's fridge!
