For Dental Use Only
Veneers are designed to cover the existing front surface of your teeth.
Veneers can be used for re-aligning, whitening, correcting the colour of a dark tooth or restoring a cracked or chipped tooth.
Veneers have approximately the same strength as natural tooth enamel, they must be well bonded to the underlying tooth. The final aesthetic outcome can be difficult to asses until the veneer has been bonded permanently to the tooth
NOTE
1.As different computers display colors differently, the color of the actual item may vary slightly from the above images.
2. Please allow 1-3 CM differs due to manual measurement.
Thanks for your understanding.

2, stir in the cup and then get it out when it is going to be transparent
3, make the gel cooled for about 5 seconds after taking it out of the cup. And then put the gel in the fangs slot so that you can glue the fangs to your own teeth, use your hands to pinch the gel to both the gaps between teeth and the inside of your teeth. This can make all of this a complete and compatible tooth socket.
4, Get the tooth socket out and cool it for a few minutes until the gel turns white.
5, repeat these steps for another fangs. Please note that these teeth sockets can be used for several times.
Kindly Note: Please do not drink hot drinks when wearing the teeth sockets. Be careful when you are making the teeth sockets, don't be scalded!

Item:3S 40A 12.6V 40A lithium battery protection board (comes with recovery function-AUTO Recovery)
Charging voltage: 12.6V - 13.6V
Scope: Nominal voltage of 3.6V, 3.7V lithium battery (including 18650,26650, polymer lithium battery)
Continuous charge current (upper limit): 20A
Model Number:3S 40A
Product weight: 4g
New upgrade version:
1, increased anti-interference function,
2, reduce the large current heat by 30% ,
3, starting power increased from 135W to 170W (3S40A)
Standard version: for starting current below 80A, power 135W below the drill.
Balanced version: suitable for starting current below 80A, power 135W below the drill.
Note 1: The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 can not start the drill!!).
Note 2: strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit.
Note 3: When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube.
Note 4: 3 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. The The Discharge test, the voltage drop faster battery that group is poor battery.
