RunestarXSame here, the packing sheet said only 4 packs of sheets too, no binder. Last time I ordered this, both the binder and sheets arrived at the same time. Massdrop didn't say anything so it's really confusing what's going on here.
DrewReaLeeCheck your packing slips. Mine only lists the sheets, while the emailed receipt clearly states binder + sheets. I've opened a support ticket.
