L to r- Precious Gold, Precious Black, Precious Silver, Precious Bronze, Precious Copper
Precious Gold- Bit darker than UD Honey. This is a very neutral gold and would go with all eye colours.
Precious Black- This is one I can't make a direct comparison too. This is quite a soft black and the metallic pigments are less noticeable.It stays on the waterline for several hours impressive for something that makes no claim to be waterproof.
Precious Silver- More metallic than UD Dime. This is the most pigmented of the liners.
Precious Bronze- Slightly lighter than UD Lucky but less pigmented. It leans quite warm, as you'd expect for bronze. I can imagine it looking amazing with green eyes.
Precious Copper- Similar to UD Bourbon without the glitter. While it looks quite warm in the swatch, sheered out it's far cooler in tone. I find I reach for this nearly every time I do a neutral look.
I've compared these to Urban Decay as I feel they are very similar, in colour and texture. The Boots pencils are very smooth and creamy; they apply wonderfully with minimal drag and are easy to get into the lashline. The high shine is more reminicent of liquid eyeliner than pencil- they seriously stand out. I prefer them to other drugstore eyeliners as they are more pigmented and sharpen better. My favourite is undoubtably the silver, which also makes a gorgeous base. With my UDPP, they last almost all day on my upper and lower lashlines, which is very good going. While they are similar colours to other brands, the extremeness of the metallic shine and the relatively good price make them outstanding to me.
These are still available on the Boots website for £13.50 and I strongly recommend them, especially if you have a £5 voucher to use up.
