Definitely not grade 10a
This hair is definitely not a grade 10a.  The hair I received does not hold a curl and is frizzy within hours.  I had it sewn in for about two months and it was in decent condition  for about 3 weeks then it began to frizz.  I wore it straight so I did not curl it initial but once I did it never held the curls.  I had it washed a styled again (pin curls this time) to see if this was the issue and by mid day the curls were frizzy.  One good note is that I had no issues with shedding.
