Joh According to the Reddit lockpicking belt list (karate belt, not chastity belt), the My-Steel locks are in the second lowest tier - decent warding, but otherwise nothing fancy. Some of them have security pins, which need a bit of picking experience, but I have no idea whether that is the case on those dainty models.
And most furniture locks I have had are not pin/tumbler locks. Either warded locks, which offer nearly no security, wafer locks, which tend to offer very little, or just things that look like locks
