Okamoto Smart Boy Slim-Fit Latex Condoms 31mm

31mm slim fit — ideal for a more compact build —— Okamoto Smart Boy is a slim-fit latex condom with a 31mm diameter, made in Japan, natural colour, 12 pieces per box. Designed for men with a more compact build who want a securer fit. Correct sizing supports reliable contraception and STI protection for more comfortable, worry-free intimacy.

31mm slim, close fitComfortable latex stretchPractical 12-pack
Key Features
Slim-diameter design: At 31mm diameter, this slender profile sits closer than standard condoms, reducing slip from an oversized fit so a more compact build feels secure and natural.
Right size, greater peace of mind: Only the right fit can fully support contraception and STI protection. Smart Boy is made for a closer fit, helping you choose a slim-size condom that works.
Natural-tone latex: Latex in a natural skin-like tone for a discreet look, with stretch and flexibility suited to everyday intimate use.
Pre-lubricated jelly finish: Factory jelly-type lube reduces dry friction for better comfort; pair with our water-based lubricants if you want still more glide.
Convenient 12-pack: 12 pieces per box — a practical 6–12 count pack size for everyday stock or sharing with a partner.
Usage Scenarios
When standard sizes slip: If regular condoms feel too big and tend to slide, try Smart Boy 31mm slim fit for a closer, more stable wrap.
Everyday bedside stock: Japan-made natural-tone latex, 12-pack — easy to keep by the bed or in a travel bag, ready when you need it so the moment isn’t interrupted.
For a closer, comfier fit: When you want a more satisfying close fit, this slim design is made for a compact build so you can focus on the moment, not the size.
Pair with lubricant: Already pre-lubed but want more glide? Choose a water-based lubricant — oil-based formulas can damage latex — for freer intimacy.
How to Use
Before use, check the individual wrapper is intact and within the expiry date
Open carefully along the notch; avoid nails or sharp objects damaging the condom
Pinch the reservoir tip to expel air, then roll down to the base
After use, hold the base, withdraw carefully, wrap in tissue and discard; do not reuse
Care & Cleaning
This product is a single-use condom. After use, wrap and discard properly; do not wash or reuse. For extra lubrication, choose products from our water-based lubricant category; oil-based lubes are incompatible with latex. You may also browse related men’s care categories to support everyday hygiene.
