Ramune Glass Bottle | Traditional Marble Soda Bottle
Our ramune glass bottle preserves the authentic Japanese soda-drinking experience that’s delighted generations since 1876. Each clear glass bottle features the signature Codd-neck design with a marble stopper that creates the unmistakable pop when opened.
Perfect for celebrations, summer gatherings, or anytime you want a refreshing carbonated beverage with interactive appeal. We craft every bottle using durable tempered glass that showcases the vibrant soda colors while the marble mechanism ensures freshness until the moment you press it down.
Traditional Design & Functional Details
Glass Construction & Marble Seal Technology
We manufacture each ramune glass bottle from tempered glass engineered to withstand the internal pressure of carbonation while maintaining crystal-clear visibility. The Codd-neck design—invented by Hiram Codd in 1872 and perfected for ramune—features a pinched neck that holds the glass marble in place once opened.
The marble itself serves as both pressure seal and interactive element. When you press the marble down using the included opener, it drops into the wider chamber where two small indentations prevent it from blocking the pour opening. This ingenious design eliminates the need for caps or twist-offs while creating the satisfying tactile experience ramune is famous for.
Opening Your Ramune Bottle Correctly
First-Time Opening Instructions
Remove the plastic wrapper from the bottle top to expose the marble and metal cap. Position the included plastic opener—shaped like a small plunger—directly over the marble. Apply firm, steady downward pressure until you hear the signature pop as the marble drops into the neck chamber.
The carbonation release creates bubbles and fizz, so hold the bottle upright during this step. Once the marble settles into the side indentations, tilt the bottle to pour. The marble may occasionally roll back toward the neck opening during drinking—this is normal and part of the traditional experience.
Dimensions & Storage Specifications
Each ramune glass bottle stands 18cm tall with a 5.5cm diameter at the widest point. The narrow 2cm neck opening accommodates the marble seal mechanism while the flared base provides stability on flat surfaces. These standardized dimensions fit most refrigerator door shelves and beverage coolers.
Store unopened bottles upright in cool, dry conditions away from direct sunlight. Glass construction protects contents from UV degradation better than plastic alternatives. The marble seal maintains carbonation for up to 12 months when stored properly, though we recommend consuming within 6 months for peak freshness and fizz.

Common Questions About Your Ramune Glass Bottle
Remove the plastic wrapper from the bottle top and place the included opener directly over the marble. Press down firmly and steadily until you hear the pop—this means the marble has dropped into the neck chamber. Hold the bottle upright during opening to prevent overflow from carbonation release.
Never use improvised tools like screwdrivers or knives, as these can crack the tempered glass or create dangerous sharp edges. Each ramune purchase includes the proper opener designed specifically for the marble seal mechanism.
The marble is permanently sealed inside the ramune glass bottle by design and cannot be removed without breaking the glass. The Codd-neck construction pinches above the marble chamber, creating a narrower opening that prevents the marble from escaping.
This permanent installation is intentional—the marble serves as both the pressure seal before opening and a functional element that stays visible during drinking. If you want to repurpose empty bottles, plan projects that incorporate the marble as part of the design rather than attempting removal.
Ramune glass bottles are 100% recyclable through standard glass recycling programs. Rinse the bottle after consuming, remove any paper labels, and place it in your municipal glass recycling bin—the marble inside does not need to be removed for recycling.
Many customers also reuse empty ramune bottles for decorative purposes, craft projects, or as small vases. The tempered glass construction withstands washing and repeated handling, making bottles suitable for years of secondary use before eventual recycling.
Our ramune glass bottle holds 200ml (approximately 6.76 fluid ounces) of beverage. The bottle stands 18cm tall with a 5.5cm diameter at the widest point and a 2cm neck opening.
These standardized dimensions ensure the bottle fits most refrigerator door shelves and beverage coolers. The 200ml serving size provides a satisfying single-serving portion without excessive volume, which helps maintain carbonation quality throughout drinking.
The marble may occasionally roll back toward the neck opening during drinking, especially when you tilt the bottle at certain angles. This is normal behavior with the traditional Codd-neck design. Two small indentations in the neck chamber are designed to catch and hold the marble, but vigorous tilting or shaking can dislodge it temporarily.
To minimize blockage, tilt the bottle gently and keep it at a consistent angle while pouring or drinking. You can also slightly rotate the bottle to reposition the marble back into the side indentations. This interactive element is part of the authentic ramune experience that’s been enjoyed for over 140 years.
Unopened ramune glass bottles maintain full carbonation for up to 12 months when stored properly in cool, dry conditions away from direct sunlight. We recommend consuming within 6 months of purchase for peak fizz and optimal flavor freshness.
The marble seal creates an airtight pressure barrier superior to many twist-off caps, which helps preserve carbonation longer. Once opened, consume ramune within a few hours, as the open bottle design (with the marble dropped into the neck) allows carbonation to escape more quickly than reclosable containers.
Children can safely enjoy ramune glass bottles with appropriate adult supervision during the opening process. The tempered glass construction is durable but still breakable if dropped on hard surfaces. We recommend having an adult handle the opening procedure while children watch, then allowing kids to drink from the bottle while seated.
The marble mechanism poses no choking hazard since it cannot be removed from the bottle during normal use. The smooth glass edges and stable base make the bottle comfortable and safe for small hands to hold. Many families introduce ramune to children ages 5 and up as a special treat with proper guidance.
