Product Overview

Monkey Flask

3.5 Fluid Oz

Serious Monkey Bizzness offers Monkey Flask, which is a pre-made synthetic urine that closely resembles real human urine, even at the molecular level. The liquid is created and tested in a laboratory using realistic ingredients, ensuring its authenticity.

Monkey Flask has the same appearance, smell, and even foams when shaken, just like real urine. This realistic physical resemblance is essential for a variety of purposes, including screenings, fetish play, and pranks.

The Monkey Flask kit comes with a 3.5 oz bottle of synthetic urine in liquid form, an eight-hour organic heat pad, and easy-to-follow instructions.

The high-quality synthetic urine in Monkey Flask is undetectable by both surface inspection and lab equipment, making it an ideal solution for passing screenings that can impact your career.

Serious Monkey Bizzness offers a range of realistic, high-quality, and affordable products, including Monkey Urine, Monkey Whizz, and Monkey Flask. Although many articles refer to all of these products as “Monkey Whizz,” there are several differences between them.
