We hope to design a product that will constantly remind us that the colorful and vast universe is actually above us.

So we tried combining coasters with astrological charts, so you can use coasters in your daily life...

Simply align the date and time vertically, and you can accurately display the current starry sky on your desktop.

You can also turn back time to your birthday or a day that is particularly meaningful to you, and let the starry sky of that day stay with you.

It consists of two groups, one with a constellation chart on the outer ring displaying the date and the other with a viewfinder displaying the time on the inner ring.

They can be used separately to enjoy drinks with loved ones. They can also be stacked together to elevate the table and protect it from heat damage.

A round coaster of a suitable size can also be used as a horoscope, allowing you to observe the stars on different dates.

What is the Plantysphere constellation wheel?

A constellation wheel is a flat tool that can be adjusted according to the time and date to view the constellations in the night sky.

Its principle is based on the changes in the relative positions of celestial bodies in the night sky after the Earth rotates and revolves.

Although modern people mostly use mobile phone star charts, the Planisphere is an important invention in the history of astronomy and is often used in basic star chart teaching.

What is the significance of "29"?

The number 29 in "STAR29" represents the maximum number of days in a lunar month, and also symbolizes the waxing and waning cycle of the moon.

Astronomy is not just about stars, but also about the rhythm of the sun and moon, making this set of coasters a symbol of time.
