Boner Expansion Pack includes two stackable TPR rings that restrict blood flow for harder erections and intensified orgasms. Compatible with existing Boner Kit components, these square donuts adapt perfectly to your anatomy while allowing endless customization possibilities for enhanced stamina and sensitivity.

Key Features:

Two stackable TPR cock rings enhance erection firmness and stamina through targeted pressure around the penis base for prolonged sexual performance and increased sensitivity during masturbation or penetration.

Square donut design with 1.3 inch exterior and 0.9 inch interior dimensions provides unique pressure distribution that maintains blood flow restriction for stronger erections and delayed orgasm.

Super stretchable thermoplastic rubber construction adapts to different penis sizes while delivering comfortable compression that enhances arousal without pinching or restricting circulation during extended wear.

Stackable functionality allows customization of intensity by using single rings for mild enhancement or combining both for increased constriction and enhanced sexual stamina during intercourse.

Compatible with existing Boner Kit components for expanded configuration options that target different erogenous zones and provide varied stimulation patterns during solo or partner sexual activities.

What it does

Slide these rings onto the base of your cock when semi-erect, and they grip snugly without cutting off circulation. Blood gets trapped in your shaft, making it noticeably thicker and more sensitive to every touch. Your erection stays harder for longer, and when you orgasm, the restricted blood flow intensifies every contraction. Dual Cock Rings work by applying targeted pressure around the base to achieve this effect.

Stack both rings together and the pressure doubles, creating almost overwhelming sensitivity. Your cock becomes hypersensitive to friction, temperature changes, and the slightest movement. Partners notice the difference immediately—you're visibly larger and stay rock-hard throughout longer sessions. Starting with one ring lets you understand how your body responds before experimenting with stacked intensity.

Specifications

  • Exterior dimensions: 1.3" × 1.3" per ring
  • Interior opening: 0.9" × 0.9" (stretches significantly)
  • Material: Premium thermoplastic rubber (TPR)
  • Quantity: Two identical stackable rings
  • Compatible: All Boner Kit components

Fit and sizing

An interior opening of 0.9" works for most men, but if you're significantly above average girth, these may feel too tight. Apply when semi-erect for easiest fitting—stretch the ring open and slide it down to the base of your cock, positioning it snugly against your body. Cockringshop specialises in products for men and couples, and our team can help you choose the right fit for comfort and function. Start with shorter wearing sessions of 20 to 30 minutes until you know how your body responds, then remove immediately if you experience numbness, discoloration, or pain.

How to use it

Apply the ring when semi-erect for easiest fitting. Stretch it open and slide it down to the base of your cock, positioning it snugly against your body. If using both rings, space them slightly apart or stack them directly together depending on your comfort level. A small amount of water-based lube on the inside edge makes application smoother and removal easier after extended wear.

Start with just one ring before attempting the stacked configuration. Keep initial wearing sessions to 20 to 30 minutes maximum until you understand how your body responds. Remove immediately if you experience numbness, discoloration, or pain. After use, rinse with warm water and pat dry.

Feature breakdown

Feature Specification Benefit Experience
Stackable design Two identical rings Customizable intensity Gradual progression possible
Square shape 1.3" exterior dimensions Unique pressure distribution Different sensation than round rings
TPR construction Thermoplastic rubber Body-safe flexibility Comfortable extended wear
Boner Kit compatible Universal sizing Endless combinations Expandable pleasure system

Who it suits

Perfect for guys who want more control over their erection quality without committing to complex devices. If you sometimes lose hardness during longer sessions or want your cock to feel thicker and more sensitive, these rings solve both problems. Beginners should start with just one ring before attempting the stacked configuration to understand how the pressure feels.

Avoid these rings if you have circulation issues, diabetes, or take blood-thinning medications. Anyone with significantly above-average girth may find the 0.9-inch interior opening too tight for comfortable wear. If you experience numbness or discoloration during use, remove them immediately and allow full circulation to return.

Tested and quality-checked

Every new line we stock is inspected by hand before it goes live — we check the build, the finish, and the materials, and we confirm it is safe and fit for how it will be used. Nothing is used for its intended purpose; it is examined, checked, and re-boxed. What that means for you is simple: you receive a piece we have already vetted, not a guess off a supplier's pallet.

How it compares

Square cock rings distribute pressure differently than round rings, hitting specific nerve clusters for unique sensations. Spiked Cock Rings add texture and extra stimulation for partners during penetration, while standard rings focus purely on blood restriction and hardness. Choose the square design if you want customizable intensity and the option to stack for deeper pressure; choose spiked variants if you prioritise added texture and partner sensation.

Please read — safety first. Put the ring on before you are fully erect and use plenty of water-based lubricant so it slides on without pinching. Keep wear time short — no more than 20 minutes while you are getting used to it, and never fall asleep wearing one. Take it off straight away if you feel numbness, coldness, a change in colour, or any pain, as these mean blood flow has been cut off too far. Never share between partners without cleaning the item first or using a fresh condom. As porous materials can harbour bacteria, use a condom over them for sharing or easy clean-up. This information is general in nature only and is not medical or professional advice, and does not take your personal circumstances into account. Stop use and speak with a qualified medical professional if you have a relevant health condition, take medication for erectile function or blood pressure, or notice pain, numbness, or discolouration that does not settle.

What you can use it with

Pair these rings with Couples Intimacy Kits to enhance partnered play during longer sessions. The rings keep your cock firmer and more sensitive throughout extended activity, while kits designed for couples provide complementary stimulation and positioning support. Using both together extends session length and intensifies sensation for both partners.
