This box is a nice surprise every month! There's always a cute theme. If I went to buy any other floating glitter pen online they are always around $10 plus shipping (usually around $4). Shipping is free with this subscription. Plus the crate includes a themed sticker, another small office supply, and a pen ink refill.
AND, I love that these pens can't be bought anywhere else. The designs are truly original! Definitely worth it.
