Turn key LED/switch

Hey guys - I'm looking for a pre manufactured part I'm hoping someone can help me.

3mm led, watch battery, switch. Ideally it could blink with a button press but not necessary. Looking to get pricing on 1000 of them for an art project.

Basically something like these "blinkies" but as small as possible.

These are blinkies: https://en.wikipedia.org/wiki/Blinky_(novelty)

Thanks!

I would search the net for "throwie". You'll be amazed.
