GOGLASSCUP Starry Edo Kiriko K9 Crystal Whiskey Glasses

We promise to use real K9 crystal material
There are many inferior imitations such as ordinary K-grade, K3, K5, K6, etc. in the market. They simply use low-end prices to attract buyers. The quality of the real products is simply incomparable to our products. We support real product comparison or channel testing.
K9 is a brand name for crystal. It is not only required to be crystal clear, but also has a transmittance far exceeding that of its peers. The Abbe number of crystals starting with K is required to be greater than 50 (the higher the number, the smaller the dispersion). Our K9 engraved cup can actually reach more than 60, and the degree of crystal clearness may be something you have never seen before. I have the confidence to say that it has surpassed the works of most of my peers. I sincerely recommend that you buy it back and compare it with the real thing.

Ordinary lead glass VS our crystal material
Ordinary lead glass
The cup body is dark, with low light transmittance and refractive index, and the cup body is made by machine molding. The cup body has bubbles or impurities, and the weight is insufficient, with a difference of about 100g
Our crystal material
The cup body is crystal clear, with high light transmittance and refractive index, and the cup body is made by high-end cold cutting technology. The cup body is highly pure and has no bubbles, and the weight is about 490g:

The edge of the cup mouth of ordinary glass produced by machine heat blow molding is convex, which makes it easier to demold.

Each of our K9 crystals is cold-cut and handmade, with a straight rim and a fire reflection that cannot be matched by imitations.

Ordinary lead glass
The lines of ordinary bottom engraving are rough and imprecise, all for cost reduction.

Our crystal material
The engraving on the bottom of our cup is fine and beautiful, and each line is hand-carved by the master.

The amazing kiriko craftsmanship, the hand-cut carved starburst texture, the clever use of refraction and interweaving to bring out the beauty of glass craftsmanship, makes the whole cup look like it is glittering with brilliance when you look down at it, and when it is turned, it is like a kaleidoscope that makes people fall into the fantasy brilliance.Product display
