Liquid Bubble Timer Height: Approximately 10cm Width: Approximately 4cm Unlike a sand timer, bubbles rise to the top as the liquid falls. It sparkles beautifully when illuminated by light. Please use it as interior decoration. The bubble speed is not constant, so accurate time cannot be measured. There is no box or bag, so it will be simply packaged. It will be packed lying on its side. Please refrain from purchasing if you are sensitive to used items. Please also read the profile details before purchasing.
