Pratt 8 Piece Straight Dilator Sounds

This sounding dialater kit has 8 pieces.
Each dialater is  11 inches (30 cm) long.
They are made out of chrome-plated brass.
Also each end is a little larger on one end than on the other, so you actually get a total of 16 different sizes.
Sizes go from 3/16 inch (.47 cm) to the largest which is  1/2 inch (1.27 cm) wide.
The kit comes in a zippered storage case.

Note: We recommend using Surgilube for lubrication.
