You should ask this is their thread.
You reply to whoever you ordered from and ask them.. They will tell you how to decode the labels or sku on them. If you threw the packaging away that had the labels then that was a bad move and now you'll know better.How do I differentiate my test c and mast e from qsc? I didn’t realise that they didn’t have any labels. (I haven’t used test c or mast before)
