The picture is misleading
The reason I gave only 3 star because the picture is misleading. What you get is only one container not two.

Perfect for home chemistry
This was perfect for an entry to endothermic vs exothermic reactions for my kids, as well as the differences in properties of different metals.

Appears to be just as advertised
It took 30 days to arrive via international mail (Italy), but it arrived and appears to be what was advertised. I was wondering about the package because the label appears oil soaked in the pictures, but it turns out that the label is just a matte, frosted finish. The packaging is perfectly fine and well wrapped. I may update when I have an opportunity to test the potassium in the vial.

Tiny amount
This is my second year buying this. I 4x as much last year. Not enough to teach six class periods with. I had to adjust my lesson plans when it FINALLY arrived (late).
