Who is this harness brief for?

The Tomboii harness brief is ideal for:

• Folks seeking fuss-free strap-on play who want a tangle-free alternative to traditional harnesses with straps and buckles.
• People exploring versatile penetration including different angles, double penetration, or using bullets during play.
• Partners with erectile difficulty looking for ways to stay intimate and engaged during sex with a wearable toy.
• Users with limited hand mobility who need an easier way to wear and use penetration gear comfortably.

How to use the Tomboii?

1. Choose the right size using the size chart—when in doubt, size up for comfort and secure fit.
2. Slide on the briefs like underwear. No straps or buckles means quick on/off access without adjustments.
3. Select your dildo or vibrator with a compatible base that fits the O-ring (1.25" to 2.25"). Some toys may require a flared base.
4. Insert into one of the two O-rings depending on your preferred penetration angle or for dual play.
5. Add bullets into the built-in pockets for extra stimulation—especially fun for the wearer or during partner play.

Great positions to try:

• On top (rider): Directional control and easy access to the toy’s movement.
• From behind (doggy): Showcases the snug fit and feels natural for thrusting.
• Straddling while seated: Great for face-to-face intimacy or chair play.

How to clean and care for the Tomboii?

• Cleaning: Machine-washable on cold gentle cycle. Place in a mesh laundry bag to reduce wear and maintain shape.
• Drying: Air dry flat or drip dry to help preserve elasticity—avoid heat or tumble drying.
• Lubricant compatibility: Works well with water-based lubes. Avoid silicone lubes near any dildo inserts if using silicone toys.
• Storage: Store in a clean, dry drawer or cloth bag. Keep separate from silicone toys to prevent material interactions over time.

Harness brief practical use info:

• Versatility: Ideal for solo or partnered use; pair with dildos, vibrators, or soft packers.
• Stimulation: Internal pocket design lets you add vibrations exactly where you want them.
• Accessibility: Easy to put on and take off—especially good for those with limited dexterity who can’t manage buckle-style harnesses.

Additional information:

• This might be suitable for folks who have trouble maintaining erection, experience premature ejaculation, or erectile dysfunction because it can be a great way to penetrate and prolong sex.
• Also, this might be suitable for folks with limited mobility in arms/hands because it can provide a way to penetrate partner with a sex toy.

Special considerations when using Tomboii:

• Needs mobility and flexibility to put it on and use.

User experience tips:

• Practice solo first to get used to how your toy fits in the O-ring and how movement feels while worn.
• Trim pubic hair around the groin lightly if discomfort is felt when removing or adjusting the briefs after sweaty play.
• Don’t overtighten with larger toys—the stretchable O-ring accommodates most, but extreme girths can warp the material over time.
• Pre-insert bullets into pockets before wearing to avoid fumbling around mid-session.
• Pair with lube-compatible dildos and avoid oil-based lubes or heavy silicone products that could degrade materials over time.
• Machine-wash it gently after every play session where lube or fluids were used—Modal fabric is ultra-soft but needs care to hold shape.
