Okamoto and Sagami Reference Table: Material, Thickness and Size
By the OOBiz product information team. Reviewed on November 9, 2026.
This table lists the facts each maker publishes for the Okamoto 002, Okamoto 003 Hyaluronic Acid and Sagami Original 002 boxes we sell. Each row links to the maker's page we checked. Where a maker does not publish a figure, the table says so instead of estimating one.

How to read the table
- Material. Polyurethane boxes are not made with natural rubber latex. Okamoto 003 Hyaluronic Acid is natural rubber latex, which may cause allergic reactions.
- Thickness. Okamoto states a class (for example, the 0.02 mm range) by its own measurement. Sagami states a figure by its own measurement and a standard thickness in microns. Neither is a measurement of every condom, and figures from different makers are not a like-for-like test.
- Length and diameter. Sagami publishes both. Okamoto names its sizes (regular and L) but does not publish mm figures on these product pages. For what diameter and width mean, see Japanese condom sizes: diameter, width and length.
- The number on the box. For what 002 and 003 stand for, see What the numbers on the box mean.
