Work out your dose in units first
Every other consideration is secondary to one number: how many clicks your usual dose takes. Run it through the calculator before you spend anything. If the answer is comfortably under 60, capacity is a non-issue and the decision is about shape and price.

Questions
- Is the metal pen worth double the plastic one?
- After three refills, yes, on cost alone. The dial action is also firmer, which makes counting clicks without looking more reliable.
- Can I use one pen for two different mixes?
- Yes, by swapping cartridges, but label them. Two identical cartridges of clear liquid are indistinguishable and mixing them up wastes both.
