Hardware-free glass storage jars with beautiful presence.
To fully enjoy the process of ingredients developing over time, we collaborated with product designer Fumie Shibata to develop storage jars with an appearance so attractive you'll want to display them. Based on laboratory glassware made by Koizumi Glass Works in Ibaraki Prefecture, we've created a neutral design that fits seamlessly into contemporary living.
Main body: Approximately φ11×17.5cm
Notice
- If syrup or similar substances remain on the lid and mouth (fitting area) when closing, it may become difficult to open. Be sure to wipe thoroughly.
- If it becomes impossible to open, warm the mouth area with hot water, then twist while wearing rubber gloves to make it easier to open.
Product Handling
- Always wash with water or lukewarm water.
- Do not use with devices other than those compatible.
- Avoid sudden heating and cooling as it is vulnerable to rapid temperature changes. This may cause breakage.
- When sterilizing by boiling, start from cold water and be careful not to rapidly cool the heated body.
- While designed for improved airtightness, this is not completely sealed, so depending on storage environment and duration, mold or moisture effects may occur.
- When lifting, hold the main body rather than just the lid.
- Do not turn upside down with the lid on.
- Dishwasher safe, but hand washing is recommended for longevity. Be careful not to overcrowd as this can cause breakage.
- Wash with a soft sponge as scrubbing hard with abrasive cleaners or metal scrubbers may cause scratches and lead to cracking.
- After washing, wipe with a soft dry cloth and store after drying thoroughly in a well-ventilated place.
- Glass is breakable, so impact may cause damage. Handle with care.
- Do not hit or scrub the interior of glass vessels hard with metal spoons or similar objects.
- Stop using items with cracks or fissures as they may cause injury.
- Cannot be recycled. Dispose according to local municipal guidelines.
- As each piece is handcrafted, there are individual variations in color, shape, bubbles, distortion, etc.

A beautiful glass storage jar with no metal fittings
In order to maximize the enjoyment of the process of growing ingredients over time, we worked with product designer Fumie Shibata to develop a storage jar that is so attractive that you will want to take it out and display it. Based on chemistry glass made by Koizumi Glass Works, a glass manufacturer in Ibaraki Prefecture, we created a neutral design that fits in with modern life.

Heat-resistant glass specialist Koizumi Glass Manufacturing
We asked Koizumi Glass Manufacturing, a glass manufacturer in Ibaraki Prefecture founded in 1912, to manufacture the products. Koizumi Glass Manufacturing is one of the few manufacturers that melts heat-resistant glass in its own factory, and is trusted by medical facilities and other organizations for its quality. They produce a wide variety of glass products by hand, in small quantities, and send them out into the world.

For making seasonal fruit liqueurs and storing tea leaves and coffee beans
You can enjoy seasonal handicrafts by pickling plums and seasonal fruits to make plum wine or fruit liqueur, or making fruit syrup, and watching the ingredients grow inside glass jars.

Easy-Seal Technology for Daily Storage
It features a "joint stopper" treatment where the friction of frosted glass creates a tight seal between the container and lid. While providing good airtightness, it has no gaskets or metal fittings, making it easy to open and close - perfect for storing everyday items like coffee beans, granola, and nuts.
