… then Master One falls in love.

Do you remember, the act of creation Othea includes Master One’s effort in merging the strongest magic to cast a spell, which will transfer all of his supreme arts to one worthy hero that can help Othea defeat the Dark Dimension. Then, he met Sophia, from out of nowhere in this infinity. They adored each other so much that the light of their love has filled the universe with bliss. Oh, it became such an insane time of an emotional roller coaster that somehow inspired them to build so many extraordinary works.

With the previous method of making Cosmo, the natural opal stones were used to represent the most realistic looks of the planets. And this time with Cosmo, let’s take a look at how we make this new keycap:

First, the glowing lines will be poured separately each mold to get a thin and sharp line, the lines will be completely dry and hard after 8-10 hours. The lines are luminously mixed so they can glow in the dark. With every stage of molding, the lines are being carefully cleaned to remove the excess resin to ensure sharpness.

Next, the planets are meticulously sculpted with lines on the surface of the clay, then we place it inside a mold and pour the resin, this step takes about 10-12 hours to finish. After the resin is completely dried, the resin ball will be cleaned off the excess resin and painted on the surface with other sculpted lines.

After a lot of steps as you can see, we have the completed details. The next step is fixed, this is a very important stage. With the lines in a keycap is a corresponding resin layer, fix the line in the right position and pour the resin then we wait for it to dry. ( This stage ensures no dust because the waiting time is equivalent to the time we pouring the lines )

Along with lines, positioning the planets are quite fascinating, the resin sphere is fixed with more resin layers to ensure the planets are located in the middle of the keycap.

At the final step, we need at least 16 hours for the keycap to completely dry. When the completed keycap is being removed from the mold, cleaning and cutting off the excess resin must be done carefully.

To make the keycap surface looks glossy and smooth, the rough finishing keycap needs to rest for 8-10 hours and sanding is performed from 1-5 respectively with different sandpaper levels from 240-2000.

The finished Cosmo is being checked again, clean the entire keycap, paste the serial number and place in the wooden box. Waiting for delivery to your house.
