Draw out a rectangle 205x74 px and fill it with some dark pink color: #D10287. Then round the corners with a value of 16px

Figure 1: Base shape
Create a second rectangle on top of the first. To keep a 4px stroke around, the second rectangle must be: 205 - 8 = 197px in width and 74 - 8 = 66px in height. Angle is modified too to 14px.
A linear gradient is applied along with an Inner Bevel effect.

Figure 2: Second shape
Duplicate 2 shapes from Step 2, place them on top of each other as in Figure 3, select them and punch Modify > Combine Paths > Punch .
