Personally I'd use a stubby calligraphy pen like a Pilot Parallel. Otherwise these are gonna be really hard to make distinct enough to read, the very-similar-height dots especially
Yeah so luckily it's designed in such a way that smaller destinctions like the height of a dot can't change the actual meaning (if a word looks like "baskxt" we'd all know what it's meant to spell because clearly a consonant isn't meant to be there)
