Due to consolidations in our First Aid Only product line, some items have new part numbers.
M660 was a 2" Triple Cut Waterproof Adhesive Tape (1 roll)
90890 is a 2" Triple Cut Waterproof Adhesive Tape 6/box
The M660 and 90890 are identical items, but we are no longer offering individual rolls of these.
The 90890 is sold and priced per box of 6, but it is now less expensive per roll.
