So we're pricing these borosilicate boiling flasks to move quickly. We've got (3) sizes, all with slightly flattened bottoms, each with a single, discreet, capacity mark in white. While the actual physical size can vary slightly, the volume remains the same. The 1000ml flask is 9-5/8" tall OA x 5-5/8" dia with a 1-5/16" ID mouth, and a lip. Takes a #7 rubber stopper. The 500ml flask is 6-7/8" tall OA x 4-1/8" dia with a 1-3/16" ID mouth, and a lip. Takes a #6-1/2 rubber stopper, but a #7 will work. The 250ml flask is 6-1/8" tall OA x 3-3/8" dia with a 1-1/32" ID mouth, and a lip. Takes a #5-1/2 rubber stopper, but a #6 will do the job.

Or the Swanee whistle. Whatever you call it, this little slide whistle (just consider it the smallest trombone in the universe) has an outsized musical history. No elevator has ever fallen in a cartoon without its accompaniment, and no jug band is complete without one, but Louis Armstrong also played one on his Hot Five recordings, and Ravel even required one in an opera score. In assorted plastic colors with a steel slide, 6-7/8" long x 1/2" dia.

You'll get (638) of these clear-glass 2ml bottles (15mm X 32mm tall) packed in a plastic sleeve. Just the ticket for essential (or even non-essential, we suppose) oils. And in these quantities there's also almost certainly a craft, art or architectural project waiting to be created. For your stoppering convenience, we just happen to have the appropriate #00 corks available in the same quantities.

These perfect little clear-plastic canisters have snug pull-off tops. They fit into die-cut circles in a black or white foam pad for display or shipping, with the cut-out foam placed inside the canisters. The foam makes them ideal for safe storage and artful display of individual coins, seeds, insects, stones (precious, semi-precious, or gall-), baby teeth, locks of hair, or any number of tiny treasures. Or toss the foam and store small amounts of anything that doesn't need a screw top. You pick (50) small canisters at 1-1/4" dia x 11/16" deep, or (12) larger canisters at 1-3/4” dia x 5/8" deep.

Clear glass, like a nail-polish bottle but with no brush in the plastic screw top. The caps we've seen are green, but only the gods of surplus know what color might be in the bottom cartons. The bottle is U-shaped, e.g. 1-7/8" tall x 1" on the flattened side x 7/8" on the rounded side, so it will sit on its side, in case you're into miniscule ships-in-a-bottle. Has a 7/16" tall neck with a 1/4" ID mouth, and holds approx 3ml.
