Home decor

Okay I don’t know what they’re actually called but I was able to find something similar. So pretty much I found these at Ross it comes in a bag they have like different stuff (dry fruit, ornaments,wood chips) it’s for decor I guess. But they all have a different smell the one I had chosen was Christmas smell (Cinnamon) I wanted to also buy a bowl and dump it there it supposed to make you’re house smell so good. But I decided not to get it at the end because I wasn’t sure how long the smell lasts? Does anyone know how long the smell on these last?
