Quick comparative post between the two eyebrow pens:
Price: Suqqu retails at around £18 for 0.7ml and GOSH retails for £5.99 for 1.2ml.
Packaging/Design: Suqqu is much thinner, and, without the lid, taller. It has a soft, flexible, bristle brush that measures at 8mm long. GOSH looks, and feels, much more like a felt tipped pen; with a longer foam type brush (measures roughly 13mm) that is soft at the tip and stiff at the base. I have two of the GOSH brow pens, and Wheat, which is shown here, leaks a little (I think it is quite noticeable in the close up picture).
Colour/Pigmentation: Suqqu comes only in two shades; 01 Green and 02 Brown, but they are enough to cover a a vast range of hair colours from blonde to dark brunette (using 02 Brown) and black hair (01 Green). Suqqu can be built up for a stronger colour pay-off, but it takes a lot more strokes to achieve what GOSH can do in one. GOSH comes in 4 different shades. The pigment is very thin, and I noticed that the colours bled when I swatched on the back of my hand. It does affect the way the pen look when used on the brows (from what I can see) but I thought I should point it out. I also noticed how red toned both 004 Wheat and 001 Dark Brown when first swatched – in fact all of them looked too red when I swatched in store. None of them are suitable for my black hair, and from what I could see, blondes may struggle to find a perfect match too.
At the end of the day, both are extremely similar products with the intent of providing longer lasting brow colour. I personally still prefer Suqqu, even though it has significantly less product for a higher price, but only because I find the colours are more universally suitable. I think the two shades that Suqqu have chosen are perfect, and the result is so natural – even when used on extremely sparse brows. GOSH is a great, affordable, alternative that is worth checking out, but the lack of ashy shades in the range is hugely disappointing to me.
