The metal case inside of the molding compound may be exposed on the top or bottom of this product.
This purely cosmetic and does not have any effect on quality, reliability or electrical specs.
Note.
OE pin (PTF,PCE,PDE,PTW,PHW,PCW,PTG,PHG,PCG)
OE pin = "H" or "open" : Specified frequency output.
OE pin = "L" : Output is high impedance.
ST pin (STW, SHW, SCW,SCG)
ST pin = "H" or "open" : Specified frequency output.
ST pin = "L" : Output is low level (weak pull - down),oscillation stops.
ST pin (SCE)
ST pin = "H" or "open" : Specified frequency output.
ST pin = "L" : Output is low level ,oscillation stops.

To maintain stable operation, provide a 0.01uF to
0.1uF by-pass capacitor at a location as near as
possible to the power source terminal of the crystal
product (between Vcc - GND).
