This is an egg shaped 10 euro R-G-B-CC-CW 'moodlight' that can be found in Action stores in te Netherlands. There is no power supply included, it requires a USB power supply to function.
The device consists of a top and a bottom shell, the main pcb with pushbutton and usb-c connector is screwed into the bottom half and the board with 3 phillips screws and the board with the LEDs is snapped with plastic clips in the top half. Nothing is glued, its all just snapped together.
Opening the device up is fairly straightforward just squeeze it hard right on the seam where the two halves meet. A wood clamp will make short work of this. Both PCBs are far enough away from the center of the device that squeezing it hard will not damage anything and the housing is sturdy enough to jump right back into shape even after opening it multiple times.
As you can see in the second picture there's little notches that you have to line up when you are snapping it back together.
