Lilian13 had offered 35 CA helmets in 100%/100% condition. However, one of them was at 98/100 (which I can accept), one in 31/62, one in 26/61, one in 22/49.
I won't hide my share of fault, as I decided to proceed with the trade as fast as possible because I had to go to work, so I did not check the merchandise.
Anyway, I wouldn't really call Lilian13 a "scammer" because of this. He had no problem in giving me the helmets first and waiting for me to come back with the stims. I just wanted people to know so they keep this in mind and check Lilian's items while trading with him.
