These are excellent quality 30ml bottles in secure packaging at a great price. There are no arguments. Additional features (long dropper, metal funnel, labels) are definitely a plus. A few caveats: the droppers don't have graduations. So if you need measurement accuracy (e.g. for sublingual tincture administration) I would look elsewhere. Of course, you can always just buy a few extra dispensers that are calibrated, BUT another caveat is that this product listing doesn't include industry-standard sizes for these bottles, so you might end up with caps that don't fit the narrow neck. (These bottles are 18mm Euro cartridges, not 20mm Boston cartridges, for those who need that info.) But if you just need a place to store your bottles without the need for precision measurements, they are absolutely OK.
