About this site

Prostate Chip Guide is an independent English-language guide to the OK Prostate Chip. It is not the official site and it is not run by OK Lab (Okada Comfortable Life Laboratory, ok-lab.net) or by anyone connected to them. The official site is ok-lab.net; this site is written by a reader.

Where the information comes from

Almost everything here is drawn from ok-lab's diary, the development diary the maker has kept in Japanese for years. Each article says which diary entry it is based on and when that entry was written, so you can go back to the original.

The diary is long, technical and written in Japanese. What this site adds is an English summary you can read from a standing start, with the maker's own wording kept where it matters.

How the summaries are written

• Nothing is invented. If the diary does not say it, this site does not say it.
• Numbers such as prices and dimensions are given as the diary gives them.
• Quotations are translated from the Japanese original and attributed.
• Step-by-step insertion instructions are not published here.

Buying from outside Japan

According to the maker's own trading-terms page, OK Lab ships overseas to countries covered by Japan Post EMS, and overseas orders are paid in advance through PayPal. Shipping cost, handling and delivery times are set by the maker and can change, so confirm the current terms on ok-lab.net before ordering. This site cannot order, ship or refund anything on your behalf.

This is not medical advice

Nothing on this site is medical advice, a diagnosis or a recommendation to use any device. If something hurts, bleeds or will not come out, stop and contact a doctor.
