The sleeves are poor quality. I was sleeving a personal deck of magic the gathering cards and found the fit either too tight (and thus unable to sleeve the card), or the sleeves would split during the sleeving process. To sleeve 100 cards it took almost three packs. I've attached a photo of the discarded sleeves.
I run a gaming store and was looking at buying bulk sleeves, but honestly based on the quality of these I'll definitely be looking for another supplier.
