We received crystals, how beautiful, how interesting, and how big they are! Compared with what we previously had. My daughter dropped a crystal from her hands in excitement as soon as she unpacked it, but it didn't break.
My kids played crystal hide-and-seek for several days in a row based on the video you created, they really enjoyed it, a wonderful idea both the crystals and the videos. And it's very suitable for birthdays. Thank you for the initiative to spread the friendship between children and crystals.
