In compliance with state health laws penis enlargement cylinders are not returnable, so size them carefully. If you have sizing questions send e-mail to nick@dallasnovelty.com
To size penis cylinders measure the circumference (the distance around, or girth) of the erect penis. To do this:
Wrap a piece of string loosely around your penis around the thickest part of your penis to measure, for some this will be the head and for others near the base.
Mark where the string crosses itself.
Lay the string next to a ruler to find the exact circumference. (Note - this method is much more accurate than wrapping a tape measure around the penis.) Penis cylinders are sized in US Inches
Find the measurement most closely corresponding to your penis circumference in the column on the left - your ideal starting cylinder size will be in the corresponding column to the right. (Cylinder Order Size is the tube's inside diameter.) If your circumference is under 4 3/4 inches we recommend you start with a 1 1/2" cylinder.
In addition to the cylinder order size we need your cylinder length, standard lengths run from 8 inches and up. (Shorter lengths will be made upon request.) The suggested length for a starter cylinder is 9 inches.
Two stage cylinders are sized by measuring with a string around the penis and balls (near where you would wear a cockring.) Use this measurement with the chart below to determine the first stage size, the second stage should be 1" - 1 1/2" larger. Two stage penis and ball cylinders are generally ordered in 10".
