To provide a packaging aid which can hold a cylindrical article in a predetermined packaging position in a packaging bag so as to prevent the article from being loose and smoothly insert and put the article in the packaging bag.

An aid body 1 exhibits a thin plate-like form, is of a size that it can receive in a state fitted in a widthwise direction in at least a packaging bag C, and has appropriate rigidity. Through holes 4, 5 to be fitted over and locked with a leg 2 of a clip B-2 of a writing implement B and a cap ball 3 protruding on a rear on a tip side are opened at two upper and lower portions along a vertical direction, and while the upper through hole is fitted over and locked with the leg 2 of the chip B-2 and the lower through hole 5 is fitted over and locked with the cap ball 3, the aid body 1 is set on the writing implement B and then it is received in the packaging bag C together with the implement B. Thus the writing implement B can be held immobile at a predetermined packaging position (a transparent part 9 on a surface sheet C-1) in the packaging bag C without play (motion) such as rotating, tilting or moving.
