Silicone is the premium material used across Birty Dird products. It is body-safe, hypoallergenic, and non-porous, meaning it will not absorb fluids. Silicone can hold fine details such as veins, freckles and textures, making it ideal for lifelike sex dolls. It also provides a smooth surface for vibrators, masturbators and other toys.

Types of silicone we use:
  • Platinum-cured silicone (sex dolls): soft, elastic, and highly realistic. Holds painted details and texture for a lifelike feel.
  • Shell-cast silicone (vibrators and sleeves): a firmer silicone layer moulded around internal motors or parts, offering durability and hygiene.
  • Liquid Silicone Rubber (LSR): injection-moulded for casings and small parts, offering smooth consistency and resistance to wear.
Care:
  • Wash with warm water and mild soap or toy cleaner.
  • Dry thoroughly before storage.
  • Use water-based lubricants only.
  • Store separately from other silicone products in a dust-free bag.

TPE (Thermoplastic Elastomer) is sometimes used for the soft inner sleeves of vibrators or masturbators. It provides flexibility and a more cushion-like feel during use.

Properties:
  • Very soft, elastic, and stretchable.
  • Creates a textured inner surface for stimulation.
  • More porous than silicone, meaning extra care is required.
Care:
  • Wash immediately after use with warm water and mild soap.
  • Pat dry, then apply a light coating of renewal powder to prevent stickiness.
  • Always use water-based lubricants only.
  • Store separately in a fabric pouch to avoid lint and dust.
Durability:
  • Less durable than silicone — can tear if overstretched.
  • With proper care and regular powdering, sleeves will last longer.

ABS is a rigid, body-safe plastic used mainly in handles, casings, and external shells of devices.

Care:
  • Wipe with mild soap and water or an alcohol wipe.
  • Avoid submerging electronic components.
  • All lubricants are safe if ABS is a contact point.

Stainless steel is durable, non-porous, and body-safe. It provides weight and temperature play options.

Care:
  • Wash with warm water and soap, or sterilise by boiling.
  • Dry fully before storage.
  • All lubricants are safe.

Tempered and borosilicate glass are smooth, non-porous, and body-safe. They can be warmed or cooled before use.

Care:
  • Wash with warm water and soap, or sterilise by boiling.
  • Handle with care — although tempered, glass can still break if dropped.
  • All lubricants are safe.

TPE (Thermoplastic Elastomer) was commonly used in earlier generations of dolls. Birty Dird has made a conscious decision not to stock TPE dolls because silicone is the superior material.

Limitations of TPE:
  • Requires constant oiling and powdering. Leaves an oily residue on the skin.
  • Cannot hold fine painted details such as veins or freckles.
  • Feels less realistic than silicone.
  • Breaks down faster, prone to tearing and fading.
  • Less durable, especially under long-term use.

Decision: We believe the future of dolls is in silicone — they are more durable, realistic, and body-safe. All new designs are released as Silicone dolls and moving forward new technology is geared to the Silicone dolls.

Cleaning:
  • Use warm water and mild unscented soap, or toy cleaner.
  • Avoid harsh chemicals (except ABS, glass, steel can tolerate alcohol wipes).
Drying:
  • Air-dry completely before storage.
  • For silicone or TPE, pat dry with a lint-free cloth and apply renewer powder if needed.
Storage:
  • Keep in a cool, dry place out of sunlight.
  • Store toys separately in bags or hard cases.
  • Larger dolls: store flat or upright with support.
Lubricants:
  • Silicone products: water-based lubes only.
  • TPE products: water-based lubes only (not stocked by Birty Dird).
  • ABS/Glass/Steel: all lubes safe.
Battery & Electronics:
  • Charge devices at least once a month, even when not in use.
  • Always dry fully before charging.
  • Store chargers separately, avoid overcharging.
Extending Product Life:
  • Regular cleaning and proper storage extend durability.
  • Inspect regularly for wear or surface changes.
