Description

Although the capacity is not large, it has a high density and heavy texture. Some customers may be unfamiliar with their heavy boar mouth, but they can also be used as decorative items.

If you are not concerned about the weight and need a larger capacity, you can choose 330ml products, but please note that the 330ml model is heavy enough for wrist exercises...

Unlike blown glass or molding, we cut large chunks of ingredients and file them to produce. This method is more expensive but will not produce any air bubbles in the process.

Heat resistant, microwave safe

.High thermal conductivity, cool to touch

The refractive index and dispersion values are the same as pure crystals, but they have much higher properties than ordinary glass. But not as much as crystal glass (lead glass). Specifically, it cannot shine like crystal glassware, but it can maintain the transparency of water.

It is easy to attract hair and dust, but it is easy to clean. It is recommended to use a microfiber cloth to clean it.

Although it looks sturdy in appearance, it is actually not impact resistant. However, due to its thickness, it is less likely to break as thin glass you use in daily life.

The characteristics are very stable and will not yellow no matter how long it is taken.
