There are at least 2 samples definitely produced: one in the original videos and another in the video released by Hyun-Tak Kim via nytimes which definitely look different. It is unclear if the sample sent to KENTECH for the analysis is the first sample or a fresh one. Young-Wan Kwon is also known to have his own sample (confirmed in MML 2023 sightings), but it is unclear whether it's distinct from other samples too.
Interviews with Q-Center folks suggest that the yield is high enough to produce a handful but not large number of samples at once, so there are probably much less than 100 samples available, which might be one of the reasons they were initially hesitant to share samples to others. (There are tons of groups want to get samples, if it's unclear.)
