Why Material Matters
Why Material Matters: The Truth About Medical‑Grade Silicone
A John Thomas Toys Guide to Body‑Safe Pleasure
When it comes to intimate products, material isn’t just a detail — it’s the foundation of safety, comfort, and long‑term wellbeing. At John Thomas Toys, we’ve built our entire brand around one principle: your body deserves the very best. That’s why every product we make is crafted exclusively from medical‑grade silicone, moulded with precision, and clearly labelled with transparent firmness ratings.
In a market where many companies rely on vague claims or misleading terminology, understanding why material matters empowers you to make informed, body‑safe choices.
What Makes Medical‑Grade Silicone the Gold Standard?
Silicone comes in many forms, but only medical‑grade silicone is engineered for prolonged contact with the human body. It’s the same class of material used in medical devices, prosthetics, and implants — and for good reason.
Non‑Porous by Design
A non‑porous material has no microscopic holes or gaps. This matters because:
- It doesn’t trap bacteria, fluids, or odours.
- It can be thoroughly cleaned and sanitised.
- It maintains its integrity over years of use.
Inferior materials — including many labelled simply as “silicone” or “silicone blend” — often contain fillers that create tiny pores. These pores can harbour bacteria even after washing, which is especially concerning for internal use.
Hypoallergenic and Free From Fillers
Medical‑grade silicone is:
- Hypoallergenic
- Phthalate‑free
- Latex‑free
- Free from softening agents or unknown additives
This makes it suitable for people with sensitive skin or allergies, and it ensures that the material won’t degrade, leach chemicals, or cause irritation.
Why This Matters Even More for Anal Use
Anal play requires exceptionally high safety standards because the tissue is delicate and does not naturally lubricate. Using inferior materials can introduce unnecessary risks.
The Perils of Inferior Materials
Products made from porous or low‑quality materials can:
- Retain bacteria, increasing the risk of infection
- Break down or become sticky over time
- Cause irritation or micro‑tears
- Be difficult to clean effectively
When used anally, these issues become more serious. The rectal lining is sensitive, and any irritation or bacterial imbalance can lead to discomfort or medical complications. Choosing a product made from non‑porous, medical‑grade silicone dramatically reduces these risks.
At John Thomas Toys, we believe safety should never be optional.
Transparency in Firmness: Our Shore Ratings
Silicone firmness is measured using Shore hardness ratings, yet many companies never disclose them. We do — because you deserve to know exactly what you’re buying.
Our products are available in:
- SR0 – Ultra‑soft and flexible
- SR2 – Soft with added structure
- SR5 – The firmest we offer, still designed for comfort and safety
We intentionally do not produce anything harder. Some brands use extremely firm silicone without explaining it, which can lead to discomfort or unsafe use. Our approach is simple: clarity, honesty, and comfort first.
Precision Matters: Why We Use Copper Moulds
Material quality is only half the story. The moulding process determines how silicone cures, how consistent it feels, and how long it lasts.
We use copper moulds because they:
- Conduct heat evenly for stable curing
- Prevent weak spots or air pockets
- Ensure consistent density throughout the product
- Deliver precise shapes and smooth finishes
This level of craftsmanship ensures every John Thomas Toys product is reliable, durable, and safe from the inside out.
Why Material Matters — And Why We Care
At John Thomas Toys, we don’t cut corners. We don’t use vague marketing terms. We don’t hide firmness levels. And we never compromise on material quality.
