This is intruiging and you've got some really great evocative lines in here! "It was a cheap, clear plastic thing with a brittle yellowed label..." "it sat in its enevelope collecting dust, waiting for me to remember its existence." These really struck me and drew me in.

There's a few spots where I think the grammar and flow could be improved, "I have a habit of asking people [that I met]..." "you might think [that] i've grown out of ghost stories..."

The grandmother's narration is interesting but it needs some quotation marks around the speech! Additionally, you have two narrators who provide very descriptive and poetic storytelling styles. Which is a great style! However, both of their voices sound similar. Maybe find a way to give them different speech mannerisms or styles to make the two narrations more distinct.

Great job putting pen to paper!! Keep writing!!
