Just Stop It!
So Pat went a little crackers and bought approximately 897 gazillion #00 rubber stoppers, enough to stop up every small test tube in every high school science lab from here to Osaka. You'll get a bag o' (1,000) of them. We know you'll find a crafty use: tiny bowling games, non-conductive earrings and necklaces, little bumper car bumpers, traffic cones for cockroaches, stubby guitar picks.... In black rubber conic sections, 1" long x 10mm (0.39") at the bottom x 14mm (0.55") at the top, or vice versa.

Childproof Cap
This white-plastic childproof cap plugs an 11/16 " bottle opening. Turned over, it fits over the thin lip of the bottle, but has a small opening/vent. We're not sure what it's venting, because we're not sure what kind of bottle it fits - but we know some of you erstwhile fans will know, and that you'll need a bunch of them.
$1.00 PKG (20)
Pat's been hanging around the medical supply house again. We now have a boatload of rubber stoppers, the kind you see on bottles of liquid medicine, crimped down with an aluminum collar. (Pat didn’t buy the aluminum collars.) The medicine is removed via a hypodermic needle through the stopper. The rubber stoppers come in gray or orange. both stoppers fit (13 mm) dia opening. The  gray are 3/4” across the top, 5/16” top to bottom. The orange are 9/16" across the top, which has a dimple in the center, and 9/16" top to bottom. Why would you want them? Because they'll fit many of the small wide-mouth and slope-shouldered bottles in our Bottlemania listing. Pat's really good!

These are left over from those scrumptious hot meals that hospitals serve. Use the trays and lids when you're under the weather, or serving someone who is.  On the other hand, we think the trays also make perfect indestructible flower pot saucers, and the lids, which have recessed handles so they can sit on their heads (which is more than you can do), would make nice wide planters themselves. Some of them say they can take heat and some say they can't but we're pretty sure they're talking about hospital ovens because they all do just fine warming up tortillas in the office microwave. Assorted unmatched colors (our choice).
