Okamoto Zero One 0.01mm Ultra-Thin Condoms - Large Size (3-Pack)

Okamoto Zero One (冈本 0.01) is a 0.01 mm uniform-thickness polyurethane condom manufactured in Japan by Okamoto Industries, designed for high tactile sensitivity while maintaining barrier integrity, sold as a 3-pack by Ways Pharmacy (UK).

Key facts

Who it is for

• Adults seeking a thinner condom with greater tactile sensation
• People with a latex allergy or sensitivity who need a polyurethane alternative
• Couples wanting both contraception and protection against sexually transmitted infections (STIs)
• Users who have found latex condoms uncomfortable, hot or irritating

Not suitable for: use with oil-based lubricants (e.g. baby oil, petroleum jelly, body lotions) which can damage the condom, double-bagging (using two condoms at once — this increases friction and risk of breakage), or reuse — each condom is single-use.

How to use

1. Check the expiry date on the foil. Tear the wrapper at the notched edge — do not use teeth, fingernails or scissors.
2. Pinch the tip to remove air, then roll the condom down over the erect penis before any contact.
3. Use additional water-based or silicone-based lubricant if required. Do not use oil-based products.
4. After ejaculation, hold the condom at the base and withdraw while still erect to prevent slippage.
5. Tie the open end, wrap in tissue and dispose in a general waste bin — do not flush.
6. Use a new condom for each act of intercourse.

Frequently asked questions

How is 0.01 mm achieved — is it really that thin?

Okamoto uses a proprietary polyurethane film process that produces a uniform 0.01 mm wall thickness from tip to base. Polyurethane allows a thinner, stronger film than latex of the same thickness. Each condom is electronically tested before packaging.

Is Okamoto Zero One latex-free?

Yes. Zero One is made from polyurethane, not latex, so it is suitable for people with a latex allergy or sensitivity. It is also fragrance-free and odourless.

Can I use it with lubricant?

Yes — water-based and silicone-based lubricants are compatible with polyurethane condoms. Do not use oil-based products (baby oil, lotions, petroleum jelly, coconut oil), which can weaken the condom and cause it to break.

Does it protect against STIs as well as latex?

Yes, when used correctly. CE-marked polyurethane condoms meet the same barrier and burst-strength standards as latex condoms and provide protection against pregnancy and most sexually transmitted infections, including HIV.

What size is Zero One Nude?

The Nude SKU is the standard fit — nominal width 52–54 mm — designed to suit the majority of users. Okamoto's larger sizes (e.g. Zero One Large) have a wider nominal width.

How should I store condoms?

Store in a cool, dry place away from direct sunlight and sharp objects. Avoid wallets, glove boxes and trouser pockets, where heat and friction can damage the foil. Check the expiry date before use.

Safety & storage

• Each condom is single-use. Discard after use in general waste — do not flush.
• Do not use if the foil is damaged or past its expiry date.
• Use only water- or silicone-based lubricants. Oil-based products can damage polyurethane.
• No contraceptive method is 100% effective. If the condom breaks or slips, consider emergency contraception within the recommended time frame and an STI check.
• Store below 25 degrees Celsius, away from direct sunlight, sharp objects and heat sources.
