OLO Condoms: Material, Country of Origin and What the Box Numbers Mean
By the OOBiz product information team. Reviewed on November 8, 2026.
The short answer
All OLO condoms we sell are made of natural rubber latex. The OLO boxes we have checked are made in China. They are not latex-free. OLO is a separate brand from Okamoto. This product contains natural rubber latex, which may cause allergic reactions. If you have a latex allergy, do not use OLO condoms.
Material
Every OLO box on our store lists natural rubber latex as the material. That includes the boxes printed 0.01, 001 or ZEROLONE and the boxes printed Hyaluronic Acid. Where a box names hyaluronic acid, the condom material listed on the box is still natural rubber latex. An older web address on our store described one OLO product as latex-free. That was wrong, and we have changed it.
Country of origin
OLO product pages that state a country of origin list China. Some older listings for OLO, including one of ours, said "made in Japan". That was also wrong. The OLO XXL box, for example, is printed in Chinese and made in China.
What 0.01 and 001 mean on an OLO box
OLO prints 0.01 or 001 on the front of several of its boxes. We read these as the maker's product names. We have not seen a thickness measurement from the maker, so we do not give a thickness figure for OLO. This is different from Okamoto and Sagami, whose boxes state a thickness class or a measured figure.
The OLO lines we sell
| Line | Box | Material | Size, as printed | Per box |
|---|---|---|---|---|
| OLO ZEROLONE 001 | Tall box printed 0.01, ZEROLONE and Hyaluronic Acid; black, red and gold boxes | Natural rubber latex | Nominal width 52 ± 2 mm, length 160 mm or more (same for all three box colours) | 10 |
| OLO ZEROLONE 001, jelly packs | Black and other ZEROLONE boxes with each condom in a round jelly-cup pack | Natural rubber latex | 52 mm nominal width on the black jelly-pack box | 10, or 3 on some boxes |
| OLO 001 square box | Square box printed 001 and Hyaluronic Acid, in several colours | Natural rubber latex | Not printed on our photos | 10 |
| OLO Man Ultra Thin | Black box with jelly-cup packs, or silver-white box with foil pouches; the condom is the same | Natural rubber latex | Not printed on our photos | 10 |
| OLO XXL | Black box printed XXL | Natural rubber latex | XXL, as printed; no width figure on our photos | 10 |
The box colour is the maker's style name. For the ZEROLONE 001 tall box, the black, red and gold boxes list the same specifications. Box text that is printed only in Chinese is set out in English on each product page.
You can see all OLO boxes on our OLO collection page. The square blue box is on the OLO 001 Blue page, and the tall ZEROLONE box is on the OLO ZEROLONE 001 page.
