I'm looking for an online source for cheese tasting flags (the tiny
ones on toothpicks) that offers specific assortments of particular
country flags. For example, I'd like to be able to order of box of
such flags, but limited to, say, ten each of the flags of France,
Spain, England, the USA, the Netherlands, and Denmark. While I've
found numerous sites that sell these flags, none that I have found
offers the option of such specificity.

"Cheese tasting flags"
Let's see:  Cheeze Whip for USA, Stilton for UK, Brie ('cause I can't
spell rocq...)for France ...  ;-)

Seriously, I see your problem, and if you only want ten of each,
places like this will only sell you 100, which is reasonable, since
ten wouldn't be worth the trouble:

   (only has France  - plus Austria, Mexico and Turkey)

USA is cheap  - I mean the flags, of course.  But that suggests the
problem of flags from different sources being different sizes:

This collection is a start:

This is probably the best choice, even if you end up with a lifetime
supply but you can choose by nation:

But that was only an excuse for the first line, since I am sure you
seen the sites already.

Myoarin, yes, I'd visited those sites, but none of them offers the
kind of specified selection that I seek. Thanks anyway!
