Before I begin the review I want to quickly state that these are not yet available in the UK
and to the best of my knowledge won't be hitting the shelves until July but I will update this post
should a date be announced any time soon!
As far as I am aware the Revlon Just Bitten Kissable Balm's retail around the $9 mark in the US/Canada
so I imagine they will more than likely be around £7 here or on par with the Lip Butters?
Also the two I have are not PR samples but ones that I had imported in to the UK, I have linked the seller
at the end of the post which I have used a good few times and had no problems.

I do like Revlon but feel the packaging and concept is a little too close to the bone to the original
product of this type - Clinique Chubby Sticks for lips.
The packaging is almost identical the only thing that really separates the two is the size difference of each pencil and the fact that Revlon has given their product a colour co-ordinated lid rather than a chrome one.
I am not complaining as I do think the Clinique packaging is great and enjoy having a lip pencil type of
product that you do not have to sharpen (Revlon has the same mechanism) but yeah all in all a little 
too close to home in the style stakes if you ask me - not that anybody did haha!
However I should mention that Tarte also do a product that is similar so perhaps this is the way forward
and that would should expect to see more brands jumping on board with this style of lip product?

Rather than doing my usual and snapping up each and every shade in the line I bought two shades,
there is 12 shades to the best of my knowledge so a good variety of shades which is always welcomed - variety is the spice of life after all.
Rendezvous is a bright coral shade that initially applies more orange than anything else
but once the glossy finish wears off , Rendezvous wore down to more of a pink shade and all traces of orange were nothing but a distant memory which is a shame as I do enjoy an orange lip.
I would deem this to a warm shade but again as this is essentially a tinted lip balm
I wouldn't worry too much about undertones and what not .

So yes these are marketed as a hybrid product - a combination of a lip stain and lip balm
and I have to agree they stain the lips with a lovely light wash of colour but are not at all drying 
due to the lip balm element which is a welcome addition as in the past I have found lip stains to be drying.
If you like lip stains then I do feel you should give these a whirl as they do stain the lips wonderfully
with a glossy sheen so you get all the colour without any of the mess a traditional liquid stain presents
they also allow you to apply with precision thanks to the nib of the pencil so to speak.
The pigmentation of Rendezvous is not as impressive as Sweetheart it applies a little more on the sheer side
however you can build it up with ease to a more full coverage finish.
Again this did not bleed or feather throughout the day, the glossy finish wore off around the two hour mark
but the staining quality for this shade lasted at least 8 hours which is pretty impressive.
The scent is the most unappealing aspect of this product it smells some what like mint
but not as fresh if that makes sense...slightly mouldy haha!

I have purposely not compared the formula of the Clinique Chubby Sticks 
and the Revlon Just Bitten Kissable Balm Stain as I will have a full post on how the compare to one
and other at a later date.
