Kagami Crystal chopstick rests

These Kagami hashioki are about 1.5" square and about 1.5" high. They are not marked but one bears the Kagami label. They came in a box with a part number on it and the box contained some literature. The design is somewhat Brutalist and vaguely resembles ice.

From the card included with tbese:

"This piece is Kagami Crystal Glass.

For thousands of years, colorless and transparent glass has been a dream of people around the world. Thanks to the development of modern technology, this dream came to fruition in lead crystal glass. As you can see, lead crystal glass, which has a noble quality, quickly became popular in Western Europe, and today it is popular as a household necessity, the perfect gift for newlyweds, and even as a rich accessory for modern life. It is. As you know, as our country's cultural life progresses, we hear the refreshing word "crystal" from time to time. Look at the crystal vase holding a single safflower near the bright window. Also, try drinking your favorite beer in a crystal tumbler with a nice texture. We hope you will feel the joy of a new life there.

Kagami

We have been known as ``Crystal'' in ``Kagami'' or ``Kagami'' in ``Crystal.'' For a long time, we have introduced lead crystal glass to Japan as the only specialized manufacturer. I'm really happy that it has become so widely loved by the time I started playing it. The design by a group of authorities in the craft world and the production by the highest technical staff in the special glass world have earned us the trust of being the best in Japan in terms of both quantity and quality, and have earned us a reputation overseas as surpassing international standards. I believe this is due to the continued warm support of many people at home and abroad who have sympathized with our progress, and I am filled with a quiet enthusiasm for further improvement.
