I was so excited when I finally got my hands on one of Revlon's Just Bitten Kissable Balm Stain pencils. I love the idea of a lip stain in pencil form. The colour I got is Sweetheart - a gorgeous bright fuchsia pink.
I have not been disappointing by this product. Being in the form of a pencil, it is super easy to apply. It's also moisturizing, not drying, as the term "balm" would suggest. And it actually does stain the lips for a good amount of hours! The colour even lasts through a drink or two, though I usually have to reapply after eating a full meal.
Another thing I like about this product is that there's no need to sharpen it - the pencil part is retractable, and you just have to twist the bottom to push more product up.
One last thing I want to mention - a very sort of random thing - is the smell. These pencils smell amazing. It's not your typical weird lipstick smell. They smell sort of minty! Every time I wear this, I notice it, and it's very pleasant!
Anyway, I highly recommend these balm stains if you like lip stains or lip products in general. They come in a pretty good range of colours, and I'm sure you could find one that suits you well. :)
