Abstract
Abstract Orthodontic archwires are packaged between pairs of flexible sheets that are releasably fixed to each other. The archwires are spaced apart from each other between the sheets and arranged in a nested array wherein a portion of one archwire is received within the U-shaped configuration of another archwire. Lines of weakness extend between adjacent pairs of the archwires for enabling detachment of one archwire from remaining archwires of the assembly when desired.
