## Emma's take

Four twisted probes for the deep end of exploration.

This isn't beginner territory — it's for experienced practitioners who know their way around urethral play and want to push deeper. The spiral texture creates unique sensation as each probe moves, while the graduated sizing lets you work your way up methodically. I love that they're genuinely medical-grade silicone with those essential safety heads for confident extraction. The extra length means you can explore depths other toys simply can't reach, making this a serious tool for serious players.

## Frequently asked questions

## What makes this set suitable for advanced users only?

The combination of extreme length (11.6 inches insertable), graduated sizing up to 10mm diameter, and specialized spiral texture makes this a serious tool requiring experience with urethral play. Never attempt without proper knowledge and preparation.

## How do I use these probes safely?

Always sterilize first, use sterile water-based lubricant generously, insert slowly and listen to your body. Stop immediately if you feel pain or resistance. The flat heads ensure safe extraction — never let a probe slip completely inside.

## What's the proper cleaning process for urethral toys?

Sterilize before and after each use by boiling for 3-5 minutes or using antibacterial toy cleaner. Store in the included case to maintain sterility. These are medical-grade silicone, so thorough sterilization is both possible and essential.

## Why are there four different sizes in this set?

The graduated sizing (7mm to 10mm) allows you to work up incrementally, starting smaller and progressing as your body adapts. Never jump directly to the largest size — progression is key for both safety and comfort.

## Can I use regular lubricant with these probes?

Only sterile, water-based lubricant should be used for urethral play. Regular personal lubricants may contain bacteria or ingredients unsuitable for internal urethral use. Sterile lube reduces infection risk significantly.
