No guys, the packaging of "RICOHJPNR02" and "CMC MAG E01" coded TDKs are COMPLETELY different. For starters, CMC completely wraps their spindles in soft plastic shrink wrap with the actual seal running from the top of the pack, down one side, across the bottom, up the otherside, and around the top. RITEK, who makes the RICOHJPNR02's, only wrap their spindles up enough so that the top cover cannot be twisted off. The plastic wrapping used on RICOHJPNR02 spindles is hard and stays the same shape after it is removed from the actual spindle (it isn't creased and wrinkly like CMC's shrink wrap), and features a perforrated strip that allows you to remove the wrapping easily. Also, the bases on the RICOHJPNR02 spindles are a glossy black, whereas the CMC spindle bases are a dark grey.
Next time you go to your local store, have a look at what's on the shelf and use my ramblings on above as a guide.
