The b-Vibe Jewel Metal Training Set is a two-piece, non-vibrating plug set built around rigid weight and a graduated diameter change. Both pieces pair a smooth zinc-alloy body with an acrylic pink heart base. The smaller plug lets you evaluate the shape and weight before considering the larger one; the larger plug is substantially heavier and wider, so progression should be based on comfort rather than on completing the set in one session.

Verified set contents and measurements
- Pieces: two graduated manual plugs; no motor, battery, app, or remote
- Materials: zinc-alloy bodies with acrylic heart-shaped external bases
- Smaller plug: 81.5 mm overall height, 34 mm maximum diameter, and 85 g weight; approximately 3.21 in, 1.34 in, and 3.0 oz
- Larger plug: 92.5 mm overall height, 40.5 mm maximum diameter, and 140 g weight; approximately 3.64 in, 1.59 in, and 4.94 oz
- Finish and shape: smooth rounded bulbs, narrower necks, and pink jewel-style heart bases
- Manufacturer time limit: b-Vibe recommends no more than 30 minutes of insertion at a time
The official guide calls the two models 3 inches and 3.5 inches while its specification table publishes heights of 81.5 and 92.5 mm. We use the measured metric heights and their approximate conversions above. Those numbers are overall heights, not verified insertable lengths; the external heart base must remain outside the body.
For another way to compare the published diameters, 34 and 40.5 mm correspond to derived circumferences of about 106.8 and 127.2 mm, or roughly 4.21 and 5.01 inches. Circumference is calculated from diameter and is not a separate manufacturer measurement. Real fit also depends on shape, rigidity, preparation, anatomy, and the amount of lubricant. Our butt-plug size guide explains why a rounded number alone cannot predict comfort.
Who this graduated metal set may suit
b-Vibe markets this as a beginner-friendly training set, but rigid, weighted metal is less forgiving than flexible silicone. The smaller plug is the starting point; the larger plug should not be treated as the automatic next step simply because it is included. This set may suit someone who already understands flared-base anal-toy safety, wants a smooth and weighty feel, and can monitor pressure and comfort closely.
If you prefer a softer material and smaller incremental steps, compare the b-Vibe Silicone Anal Training Dilator Set. For a single flexible manual plug, see the b-Vibe Slide Silicone Butt Plug. If you are specifically comparing rigid metal designs, the njoy Pure Plug Medium is another distinct shape and size; do not assume that comfort with one metal plug guarantees comfort with another.
Conservative setup and progression
- Inspect first. Check the metal surface, neck, and acrylic base for chips, cracks, rough spots, corrosion, separation, looseness, or sharp edges. Do not use a damaged piece.
- Begin with the smaller plug. Use the larger piece only after the smaller one can be inserted, worn briefly, and removed without forcing, lingering pain, or irritation.
- Use ample lubricant. The b-Vibe guide says to lubricate the bulb and anus and to begin with a well-lubricated finger. It does not name a required lubricant base. Check both labels for zinc-alloy and acrylic compatibility; a simple water-based anal lubricant is the most conservative starting category when the labels agree. Our water-based lubricant guide covers viscosity and reapplication.
- Move slowly. The narrow tip and rounded bulb do not eliminate the need for preparation. Pause if the body tightens. Never force the widest point past resistance.
- Keep the base external. b-Vibe explicitly warns not to insert the toy beyond the flared base. The heart base is a retrieval and retention feature, not an insertable portion.
- Limit the session. Follow b-Vibe’s maximum of 30 minutes at a time. A shorter first trial is reasonable because the material is rigid and the larger plug weighs 140 g.
Remove the plug immediately for sharp or increasing pain, burning, bleeding, numbness, tingling, cold tissue, marked color change, loss of sensation, dizziness, or a base that begins to pull inward. Do not use numbing products to mask feedback. If a plug cannot be removed promptly, or bleeding or severe pain continues after removal, seek urgent medical help.
What the weight and rigid surface change
The larger plug is about 65% heavier than the smaller one. That does not translate directly into a predictable sensation: body position, movement, muscle tension, neck fit, and the base’s contact with the body all matter. Weight can make movement and removal feel more demanding, so test the plug while alert and in a position where you can reach the base easily. Do not sleep in it, drive with it, exercise in it, or use it when alcohol, medication, recreational drugs, injury, or reduced sensation could interfere with monitoring.
The official product page promotes temperature play, but the current user guide gives no approved heating or cooling method or temperature range and tells owners to store the set away from heat. We therefore do not provide a home heating or cooling procedure. Do not use an oven, microwave, stovetop, open flame, boiling water, or freezer. Contact b-Vibe for product-specific temperature instructions before experimenting.
Partnered use
For partnered play, agree on the selected size, pace, 30-minute maximum, stop signal, and who controls insertion and removal before starting. The wearer must be able to stop immediately. The guide describes the set for solo play, foreplay, or sex, but that is not a guarantee of fit, comfort, or orgasm. Our guide to using sex toys with a partner covers consent and control in more detail.
Cleaning, drying, and storage
The b-Vibe manual directs users to clean before and after every use with an antibacterial toy cleaner or warm water and antibacterial hand soap, then air-dry or towel-dry thoroughly. Follow the cleaner’s directions and rinse away residue. The product page labels the set 100% splashproof, but that label does not establish dishwasher safety, sterilization, or submersion. Do not soak it or use boiling water, bleach, alcohol, abrasive pads, or mixed cleaning chemicals unless b-Vibe provides a product-specific instruction that says to do so.
After drying, inspect the junction between the metal body and acrylic heart base. Store both pieces away from heat, direct sunlight, moisture, and items that could scratch the finish. Keeping them separated in a clean pouch reduces surface contact. See our full guide to cleaning and storing sex toys. Retire a plug if the base loosens, the acrylic cracks, the finish flakes or corrodes, or any surface develops an edge that could catch skin.
Important limits
This set is an adult novelty, not a medical device or treatment. It does not reduce inflammation, guarantee easier penetration, or promise a particular sexual result. Do not share it without a barrier and complete cleaning appropriate to the materials. If you have active pain, bleeding, unexplained symptoms, recent surgery or injury, or a condition that affects sensation or healing, ask a qualified clinician whether internal use is appropriate before using the set.
