Material: glass
Color: blue, light blue, purple
Size: 8.8x16cm
Duration: 15 minutes
Package includes: 1 x hourglass timer
Tips:
*The hourglass production process will cause a timing error of about 10%
*Sand is powdery and will have static electricity, so sand sticking to the wall and occasional jams are normal. Flick a few times, leave it for a period of time or put it in the sun on a sunny day, and it will alleviate it.
