I find it weird that there is a discrepancy in price when it comes to the official Huawei P20 Pro Silicon Case.
On Lazada , it is selling for S$28 whereas, at the Huawei Concept Store in 313@Somerset, it is selling for S$38.
Huawei Concept Store at 313@Somerset is being operated by Jim And Rich Trading  and the store on Lazada is also run by them. I thought the price is controlled, but I guess I am wrong.
Sadly, I bought the case for S$38 at Huawei Concept Store in 313@Somerset as I have only two working days left before flying to Japan.
The official Huawei P20 Pro Silicon Case comes in three colors, Black, Blue, and Pink. I got the Blue to match my P20 Pro in Midnight Blue.
There are two small holes at the top of the case. One for microphone and one for the IR blaster.
Similar to the Apple iPhone X Silicon Case , this case also doesn’t cover the bottom of the phone.
I recommend using a case with the P20 Pro. If not when your phone is placed on the table facing up, it will wobble when being pressed.
