What each material is like to live with: hardness, weight, surface finish, how well it survives cleaning, and where it tends to fail. Materials and formulations have changed over the years, so treat these pages as a record of a moment and check the maker's current listing before buying.
Materials and what each is like
When did Blue Chips go on sale? | The range launched in stages in 2021 [OK Prostate Chip]Blue Chip releases were announced in stages from July through November 2021.
Can I buy a stainless steel prostate chip? | Two models are on the current list [OK Prostate Chip]OK Lab, a small company in Japan, began stainless steel chip sales with limited trial batches.
Will ceramic chips clean easily and avoid sticking? | The maker reports benefits, with limits [OK Prostate Chip]Mr. Okada reports easier cleaning and less sticking, but these are his observations.
Will an unglazed ceramic chip feel rough? | The diary reports friction, injury, and changing sensations [OK Prostate Chip]Unglazed ceramic felt rough in the diary accounts, which included injury and bleeding.
Can silicone irritate genital skin? | The maker reports comfort, but also injury [OK Prostate Chip]Mr. Okada reports comfort from external silicone parts, alongside injury from an elastic ring.
Will a resin screw chip stick? | The maker reported less sticking, but size mattered [OK Prostate Chip]Mr. Okada reported less sticking with resin screw chips, although a larger version moved less during use.
Is 0.2mm wire too thin? | The maker added flexibility and a nylon backup [OK Prostate Chip]Mr. Okada found 0.2mm wire more flexible, but his stopper tests also identified a limit under forced pressure.
Why switch to nitinol thread? | The maker sought less slack, then kept nylon outside [OK Prostate Chip]Mr. Okada explored nitinol thread because nylon could become slack, disappear from view, or tangle around connected chips.
Are biocompatible resin chips safer? | Early tests did not establish long-term safety [OK Prostate Chip]Mr. Okada reported promising resin prototypes, but the entries do not establish a safe duration for prolonged use.
Is my chip's resin fully hardened? | Mr. Okada says full strength can take months [OK Prostate Chip]Mr. Okada says full resin strength can take months, even after initial hardening.
Stainless steel ring chip: will it feel gentle? | Small sizes can still feel demanding [OK Prostate Chip]Ring chips can feel demanding, and the diary records irritation and unexplained black residue.
Can I customize a ceramic chip? | The maker says molds limit size and shape changes [OK Prostate Chip]The maker says existing molds limit ceramic chip sizes, shapes, and bump positions.
Will my ceramic chip come out the right size? | The maker allows for firing shrinkage [OK Prostate Chip]Mr. Okada reports that ceramic chips shrink during firing, and errors in the allowance can affect their finished size.
Can I leave a resin chip in for hours? | The maker reported problems and later design changes [OK Prostate Chip]Early resin designs drew reports of discomfort and bleeding during continued wear.
What is the silicone-covered thread made of? | Nylon inside silicone, with a later wire option [OK Prostate Chip]The original cord enclosed nylon in silicone; the maker still reported dust and friction drawbacks.
Is the aluminum prostate massager bare metal? | Silicone covered it, but early seals failed [OK Prostate Chip]Mr. Okada found aluminum prone to scratching and reported sealing problems in early rectal chips.
Do glass prostate chips slide better? | The maker reports less friction, with limits [OK Prostate Chip]Mr. Okada reports less friction with glass, but smoother chips can also slip away from their intended position.
Why use shape memory wire in a prostate chip? | Flexible connections retain a preset shape [OK Prostate Chip]Shape memory wire (metal that returns to a preset shape) allows connected chip parts to bend.
Can a resin chip stick inside the urethra? | The maker reports sticking, especially during long wear [OK Prostate Chip]Mr. Okada and a customer linked resin sticking during longer wear to difficult removal, discomfort, or bleeding.
Is 0.03mm wire better than 0.05mm? | Each presented different problems [OK Prostate Chip]Thinner wire felt softer to Mr. Okada, but prototypes brought bleeding, breakage, and manufacturing problems.
Nitinol vs nylon thread: which is better? | The maker found reasons to combine them [OK Prostate Chip]Mr. Okada describes nitinol (metal that returns toward its earlier shape) as springier than nylon, with no breakage guarantee.
Can ceramic chips be made to order? | Molds help, but shape and timing limit custom work [OK Prostate Chip]OK Lab, a small company in Japan, developed ceramic chips after glass breakage reports and difficult early production.
Does epoxy get stronger with time? | The maker reports gains over months, with limits [OK Prostate Chip]Mr. Okada reports that epoxy (a resin) keeps hardening for months, but age does not prevent every failure.
Can silicone irritate the urethra? | The maker reports friction problems [OK Prostate Chip]Mr. Okada reports silicone friction and irritation, particularly when moisture declines during prolonged contact.
Is thinner prostate chip wire gentler? | The maker usually found it gentler [OK Prostate Chip]Mr. Okada generally found thinner wire gentler, but position and coverings also affected discomfort.
Can a ceramic prostate chip break? | Wire reinforcement aims to keep pieces connected [OK Prostate Chip]Ceramic can still crack; Mr. Okada developed reinforcement after a broken tip remained inside a customer's bladder.
How thick are the wires and tubes? | Sizes depend on the part [OK Prostate Chip]Wire and tube dimensions changed with each part; thinner tubing did not always feel milder.
