Why you’ll want one

• Steps from 6mm to 13mm so you can check sizing gradually and confidently.
• Buy the right size first time (less disappointment, fewer “oops” orders).
• Stainless steel for a smooth finish and easy cleaning.
• Beginner-friendly when used patiently — and still useful if you’re planning to size up.

Quick tip

If you’re between sizes, choose the option that matches your comfortable step — not your “I can force it” step. Comfort is what makes this fun (and repeatable).

How to use

1. Start small and take your time.
2. Use plenty of suitable lubricant and move up only when it feels comfortable.
3. Make a note of the step(s) that feel best, then choose a sound diameter to match.

Safety & hygiene (keep the fun, skip the drama)

• Clean thoroughly before and after use.
• Don’t share between partners.
• If anything feels sharp, painful, or “off” — stop and reassess.
• If you’re prone to irritation/infections, be extra cautious and consider checking with a clinician.

What it is (and what it isn’t)

• It is: a sizing tool to help you choose an e-stim sound diameter confidently.
• It isn’t: an electrode or a stim device — it doesn’t deliver stimulation on its own.

FAQ

Will this work with my e-stim box?

This is a sizing tool, not an electrode — it doesn’t connect to a box or deliver stimulation. It’s used to help you pick the right sound size before you buy. But attach a sticky pad electrode to it, and you can use it as an electrode.

I’m new — is this worth it?

Honestly? Yes. If you’re buying your first e-stim sound, this can help you avoid ordering the wrong diameter and make your first “real” purchase a lot more confident.
