Care and Maintenance for Your Product
Care and Maintenance for Your Product
To ensure the longevity and hygiene of your product, we recommend washing it with neutral or mild unscented soap and water before and after each use. For a deeper clean, you can boil the product in water for 2–3 minutes, taking care to let it cool before handling, as the silicone will retain heat. If desired, you can apply corn starch after cleaning to maintain its softness and prolong the life of the silicone. Store your product in a dust-free, dry environment to keep it in optimal condition.

Before using it in a public bathroom, we recommend practicing at home as many times as necessary. It can take a while to get used to urinating correctly in an STP, don't be discouraged if it doesn't go right the first time! Using this packer with a harness makes its use easier.
- Place the cup tightly on the body to avoid any spillage.
- Lift the STP shaft straight, aim and begin to urinate slowly, controlling the flow to prevent the cup from overflowing.
- When you finish urinating, tilt the cup downwards so that any rest of the urine slides out.
- Wash and dry your STP packer after every use.

Okay so I haven't used him for anything but packing yet but this is amazing. I got the duchamp 3 in one for pack, play, and stp.
It looks even better in person, so realistic I almost cried a little seeing myself wearing it. This store is worth it, the quality is very high and after seeing the results first hand I'd call it a bargain. I'm coming back here for any new packer needs I have and reccomending it to friends
Great product, looks very realistic. Fast international shipping too.
It is an okay product, doesn’t align with my anatomy but maybe it works for others.
Can’t wait to wear it
Great customer service, great product!
