Lucky Beth 60 mins Cute Fat Chef Shape Mechanical Kitchen Timer Cooking Count Down Material:plastic. Size:9.6x6.6cm(3.8"x2.6") Usage: The timer clockwise circle to zero scale (do not exceed one circle, otherwise the product will damage), and then counter-clockwise back to the time required, the timer will then send crisp tone (note not screwed directly to the time required, but you need to clockwise circle to zero scale, and then go back to the time required screwed required) Note: This is a kitchen timer to remind the role when cooking, not alarm, ringing will not take very long about 3-5 seconds. If you do not follow the above instructions using said first clockwise, then counterclockwise rotation operation, but direct reverse operation, will cause the product useless. Cons: Because it is a mechanical clock, there may be 1-16 minutes error, not shatterproof. Cute cartoon characters, bright colors. Not only has regularly reminded of function, but also as a decoration! The mechanical clockwork timer principle, easy to use, no batteries! Never strike!Perfect to your friends as a gifts
