I have 0.4 pilot juice up that I use for school, and I'm almost out of ink. if I were to get the correct refills i'd have to wait at least a mont before arrival, and I'd need it earlier I'm forced to either buy a 10 pack refill, or I could buy the 0.38 refills

would there be a genuine problem with it? inclined not to think so as the measurements are so similar, but if they exst as different there probably is a reason. if any of y'all know if it'll work or not pls tell me
