I love this case! It is sparkly (a true gold, not brassy) and not cheaply made. I love how thin yet durable it is. I've used it everyday since receiving the case and the leopard print has not faded. Worth every penny!

Ex Output:
positive

Ex Input:
I dont use this for an apple pencil. I use it for my vape pen, and it's perfect. Of course I bought all this stuff right before the news came out that vaping has been killing people... so now it's a lovely case to keep the unused vape pen in. Yep.

Ex Output:
positive
