Our specially manufactured microfiber terry inserts are made of 3 layers of soft and
very absorbent microfiber. They are chemical free.  The small insert is 12 inches
long and the med-large insert is 16 inches long and has been designed to fit perfectly
in pocket diapers, one-size diapers, and fitted pocket diapers.  Happy Heiny's has

recently changed their insert shape....some are contoured as above and some are

rectangular.  The shapes are noted below.
