queasy @BG342245736 I used google translate to translate what you wrote so pardon if my answer is not quite correct: The keycaps came in a very nice box with the keycaps in thick foam, so they are very well protected!

queasy @BG173347514 Its the Chinese Ink Painting keycaps: https://www.banggood.com/134-Keys-Chinese-Ink-Painting-PBT-Keycap-Set-OEM-Profile-Sublimation-Japanese-Korean-Custom-Keycaps-for-Mechanical-Keyboards-p-1884018.html?rmmds=myorder

queasy @Petr Kopčo Try to search for Japanese Minimal Cherry Keycap - and you should find it. Multiple vendors/shops have them in stock.

queasy Update: The product stopped working after 3 months of very light use. I used it perhaps 2 times in a week.The motor stopped working and the battery stopped charging, fortunately Banggood was kind enough to partly refund the purchase.

queasy Atips/trick. When you want to disassemble the board - unscrew all screws. Then very gently bend to left and right side of the case and the plate should pop out. Once the plate is out, the pcb will fall out if you flip the case upside down (beware of the battery connector on the pcb if you have the wireless version).
