The Big Boy Silicone Vibrator by NANMA Corporation

The Big Boy Silicone Vibrator by NANMA Corporation is a 7-inch flexible silicone vibrator with 10 distinct vibration patterns, designed for targeted G-spot stimulation. Its bendable shaft holds position once set, and waterproof construction suits shower or bath use. The LED display cycles through rhythms without guesswork.

About this product

The Big Boy Silicone Vibrator by NANMA Corporation combines a bendable internal structure with medical-grade silicone to create a vibrator that adapts to your body rather than forcing your body to adapt to it. Once you bend the shaft to the angle you need, it holds that position while the motor delivers any of its 10 vibration patterns. Unlike rigid vibrators that demand perfect aim, this flexible design means you set it once and stay focused on sensation rather than repositioning.

The waterproof construction seals the motor completely, making it safe for shower, bath, or pool use without risk of damage. An LED indicator displays which of the 10 patterns you're currently using, so you can switch modes by feel or sight. Medical-grade silicone feels natural against skin and resists staining, discolouration, and odour when cleaned properly.

Notable features

• Bendable shaft: Flexible internal core allows you to adjust the angle precisely and maintain it throughout use without constant readjustment.
• 10 vibration patterns: Range from gentle teasing rhythms to intense pulsing modes, each distinctly different from the others.
• LED pattern display: Illuminated indicator shows which mode is active, eliminating confusion when cycling through rhythms.
• Waterproof body: Fully sealed design permits use in water and simplifies cleaning under running water without worry.
• Medical-grade silicone: Non-porous, body-safe material resists bacterial growth and maintains integrity through years of use.

Controls, settings and use

The Big Boy operates via a single button on the handle. Press once to power on—the vibrator starts at pattern one. Each subsequent press cycles to the next pattern; the LED display indicates which of the 10 you're using. Hold the button to power off completely. Before first use, charge the battery fully using the supplied USB cable; a full charge typically delivers several hours of runtime depending on pattern intensity.

Bend the shaft gently until it reaches the angle and depth you prefer, then hold it in place during use. The flexible core maintains the position without manual support. Unlike metal vibrators that conduct temperature and transmit noise through rigid frames, this silicone design absorbs vibration noise and feels naturally warm. Rinse thoroughly under warm water after each use; silicone can be dried with a lint-free cloth and stored in a cool, dry place.

Is it a good match?

Care and storage

Rinse the entire vibrator thoroughly under warm running water immediately after use. Use a soft, damp cloth to wipe the silicone clean, paying attention to any seams or the handle base where moisture might collect. Dry completely with a lint-free cloth before storage. Store in a cool, dry place away from direct sunlight or heat sources. Keep the USB charging cable in a dry location. Do not submerge for extended periods or use harsh soap—warm water is sufficient.

Where to read more

Understanding how vibration patterns affect sensation and pleasure takes practice; different rhythms suit different moods and body responses. Our blog explores how to get the most from pattern-based vibrators and answers common questions about bendable designs.

What to expect

The bendable shaft takes a few sessions to master. You might spend your first use experimenting with different angles rather than focusing purely on sensation—that's normal. Once you find your preferred bend, subsequent sessions flow more naturally. The shaft maintains its position reliably, so repositioning is unnecessary unless you deliberately adjust it.

The 10 vibration patterns feel genuinely distinct from one another. Some deliver broad, rumbly stimulation while others offer faster, more pinpoint patterns. Most people find their favourite within the first few patterns and return to it, though exploring all 10 across different sessions often reveals new preferences. The pulsing patterns build intensity gradually rather than delivering one flat speed, which creates a more dynamic sensation.

Charging takes 2–3 hours from empty; battery life on a full charge ranges from 4–6 hours depending on pattern intensity. Lighter patterns consume less power than the highest settings. The vibrator produces minimal noise compared to rigid plastic toys, making it discreet during use.

The medical-grade silicone does not stain or develop odour when rinsed and dried properly. Over time with frequent use, the material may develop a slight surface texture change, but this does not affect performance or safety. Most users report no degradation in vibration quality after a year of regular use.
