Old Powder Flask. Ottoman?

[JacobC]

A friend recently gave me this old powder flask - evidently it was an antique store find and no one had any info about it. I have learned a lot browsing here in the last few weeks.

I see where others have posted images of a similar flask of Ottoman origins. With my flask, one side is plain while the other side has decorations, including an eight-pointed star. My understanding is that an eight-pointed star has Ottoman/Palestinian/Islamic significance?

I appreciate any info about this flask's origins, age, and the meaning of the symbology/decorations. Thanks!
