20 Glass Stirring Rods Stir Stick with Both Round Ends 12 Inch Long 7 mm Diameter and 6 Inch Long 5 mm Diameter, 10 for Each Size for Lab Kitchen Science Education and Stir Hot Cold Beverage Cocktails

None came broken, easy to clean and very sturdy

Great product at great price delivered as promised, highly recommended A1++++*****

I bought these because I have certain powders that must be mixed with non-metal utensils, but I now find myself stirring everything with these cool glass sticks! There's just something about stirring with glass that is so satisfying; I'm not sure how to describe it; but I wish that I had bought these years ago. They seem quite sturdy; I have not broken any in the several months since buying them. They arrived unbroken, although the packaging was not that great so I can see why others complained about it.

I like how the stirrers are non sticky

I use them for everything from my coffee to hot sauce mix

The smaller ones are nice for large coffee cups, but the longer ones are a little too long in my 20oz insulated cups. They work, but stick out a little farther than I'd like.

The media could not be loaded. Please change your ad! Many of us are buying your product because we need 5mm AND 7mm rods!!! Unfortunately, the large rods are NOT 7mm... They are the same width as the small ones! Deceptive advertising! Can't return them since I used some before I realized they weren't the correct size AND now my design is ruined. Days worth of work gone in a jiff. BUMMED. I guess I should've measured myself but I ordered these for the sizes specifically... this REALLY sucks!!!! :(

If exact diameters are important to you, don't buy these. Diameters BOTH ~6 mm. The shorter ones are 4" NOT 6".If you want stirring rods for stirring, these are FINE. Clear glass, well packaged, none arrived broken, chipped, or even cracked.The 12" ones are about 11 3/4My problem is that a 4" (100 mm) stirring rod is far too short to safely stir any beaker above 50 mL
