Dr. Kaplan's Head Enlarger is a cylinder designed to expand the penis head to match the penis shaft, after a regular pump session. Our Head Enlarger should be used in conjunction with the First and Second Expansion Cylinders and a Pump System, some men also enjoy it for self-pleasuring and masturbation (for best results, do not masturbate before or after a pump session). All of Dr. Kaplan's cylinders are injection molded, they are one piece, durable, and are easily cleaned. They have no seams and do not crack.
IMPORTANT: This item will only fit up to 5.25" erect head circumference.
