These already disappeared from the shelves here (at least in my local drugstores), since they were replaced by the Matte Inks, which are Maybelline's second and a lot more successful attempt at a liquid matte lipsticks. I got mine a swap from Canada, but they can still be bought online (for Slovenes on Salma and Spletična).
Formula and finish: It's a lipstick-lip gloss hybrid with a similar formula to Revlon's short-lived Moisture Stains, as it has a similar almost cooling/watery feeling on the lips. Finish is creamy and it doesn't set to a matte one, but you can blot it. Due to not being matte, it's much more comfortable on the lips than Maybelline's proper matte lipsticks Matte Inks.
Shade: My shade is 25 Fuchsia Ecstasy, which is a bright warm fuchsia. It's one of those intense hot pinks that stains a lot, so you can't just take it off, as the dry parts of the lips will stay tinted.
Staying power: Matte Inks are some of the most long-lasting lip product I've tried, but these that are their predecessors aren't nearly as good due to never drying matte. Since my shade is a fuchsia, it lasts a long time, but most of the colour wipes off soon due to a creamy formula.
Packaging: The doe foot on this is quite large, but precise, so it's a good shape for application.
Price and availability: These aren't sold in Slovene drugstores anymore and the same possibly goes for other European countries, but you can get them online. They cost 6.25 € on Salma.
I skipped these for a reason and now that I've tried there, I can see why they aren't terribly popular. Despite the matte in the name, these aren't matte, at least they don't dry matte as much as wear off to a matte stain, similar to Revlon's Ultra HD. These are simple creamy liquid lipsticks and that's it.
Have a great day!
