Research Methodology

Since STP packers come in different shapes, sizes, and materials, it's important to choose one that meets your specific needs. Here are some key factors to consider:

✔️ Ease of Use – Some STPs have a steep learning curve, while others are easier for beginners. The size and shape of the funnel play a big role in functionality.

✔️ Realism & Aesthetics – If having a lifelike appearance matters to you, opt for an STP with detailed textures, veins, and natural skin tones.

✔️ Comfort & Fit – The STP should sit comfortably in your underwear without shifting. Some STPs require special harnesses or packing underwear.

✔️ Material & Durability – Medical-grade silicone is the best choice for hygiene and longevity. Avoid porous materials that can trap bacteria.

✔️ Leak Prevention – A well-designed funnel prevents spills and ensures smooth urine flow. Some designs may collapse under pressure, leading to leaks.

✔️ Ease of Cleaning – Since STPs come in contact with urine, they should be easy to clean with warm water and mild soap.

✔️ Price & Value – STPs range from $10 for a basic model to $500+ for high-end prosthetics. Finding a balance between quality and budget is key.
