Featured I've Heard Of A Ship In A Bottle But Never...

A pair of dice? Tiny ones too. Anybody ever seen such a thing?
Bottle is glass, no seams. Find from an estate junk drawer.

 

We've seen a few similar things:

Your example, just a novelty item, or a component of a boardgame? Who can say... Here's a sort of related piece from a circa 1940s boardgame -- two standard (16mm) dice sealed in (now-clouded) plastic:

 

If I knew anything about the standard arrangement of spots on dice I could probably answer this myself, but does a combination for 7 show on any of the sides? You could roll these; do they have enough space in their to really change position?

 

Might look up 'impossible bottle' - have seen all sorts of things, including dice, in bottles, probably pennies more than anything else...

I don't think they are uncommon.
Novelty or Souvenir item.
I've seen them before, think I may even have some somewhere.

 

Suitable for gambling on railway cars and the like. I'm guessing that was the original use. You could roll two dice without having the dice taking a dive on you.

 

If the dice don't make a lot of noise when they bounce inside, I'd guess they're made of a soft plastic and were squeezed to get them in the bottle.

 

The dice are either celluloid or bakelite, hard to tell inside the bottle. There isn't really enough room for the dice to sit side by side unless the bottle is actually on it's side. They don't roll around too easy but they do roll. I figured it's some older novelty type thing. Thanks for the replies everyone.
