Okamoto 001 vs 002 vs 003: What Is Different
By the OOBiz product information team. Reviewed on November 8, 2026.
The short answer
- Okamoto 001 and Okamoto 002 are polyurethane (Okamoto calls it water-based polyurethane, 水系ポリウレタン). They are not made with natural rubber latex.
- Okamoto 003 is natural rubber latex, which may cause allergic reactions.
- The number is Okamoto's thickness class: 001 is the 0.01 mm class, 002 the 0.02 mm class and 003 the 0.03 mm class, each by Okamoto's own measurement.
All three are Okamoto Industries, Inc. products. The boxes we sell are Japanese retail boxes imported from Japan.

Okamoto describes each line as a thickness "class" (ミリ台): a thickness in that range, by its own measurement. It is not an exact figure for every condom. More on this in What the numbers on the box mean.
What the number does not tell you
The number does not tell you the material. 001 and 002 are polyurethane, but 003 is latex. Okamoto also sells other boxes that carry no thickness number at all. Always read the material line on the box.

Common questions
Is Okamoto 001 latex-free?
It is not made with natural rubber latex. Okamoto lists the material as water-based polyurethane.
Is Okamoto 003 latex?
Yes. Okamoto 003 is natural rubber latex, which may cause allergic reactions. If you have a latex allergy, do not use it.
Which is thinner, 001 or 002?
By Okamoto's own classes, 001 is the 0.01 mm class and 002 is the 0.02 mm class. These are the maker's figures for each line.
What lubricant can I use with them?
Follow the instructions printed on the box and the leaflet inside. With any latex condom, oil-based products such as petroleum jelly or body lotion can weaken the latex (CDC).
For the difference between the two materials, see Polyurethane vs natural rubber latex condoms.
