My father is an insulin dependent diabetic who faithfully checks his blood glucose regularly. The little bottles containing the diagnostic test strips make perfect storage vessels for loose herbs, small oil blends and other small witchy supplies. My father gives me his empty test strip bottles for my incense work.
The bottles are well made (One Touch Ultra), smooth black on the outside, smooth white on the inside, and each has a tightly sealing attached snap cap. Soak off the label, and they are perfect witchy little bottles! Best of all, the act of recycling (by both my father and myself) introduces another positive element (balanced environmental stewardship) into my magic.
This is very good.
