hello :)
this should be 3 star, she is sending nice stamps, maybe some have the fixer mark, but this is normal in used stamps, even in mint stamps
with this 2 star, this lady is at risk of being out the club if she ever has again 1-2 star in next 9 exchanges
for the fairplay of this club, I think you should rate again at least, to 3 star
thanks and I hope you understand my comment
