How to choose a TONYMOLY Back Gel eyeliner
Back Gel is TONYMOLY's gel eyeliner line on skinsli, with a base version, a Z upgrade, a Long Brush format, a proof liner, and a flat-tip liner. Here's how the listings differ.
Back Gel Eyeliner is the base 4g liner
The base Back Gel Eyeliner is listed at 4g, including a version specified in shade 01 Black, and is the starting point of the line.
Back Gel Eyeliner Z comes in 7g and 4g
The Z version of the eyeliner is listed at both 7g and 4g, giving a larger size option alongside the standard 4g size.
Long Brush liner ships as a standard tube or numbered packs
Back Gel Eyeliner Long Brush is listed as a standard 4g tube, plus two separate numbered listings: No. 1 in Black as a 3-piece pack, and No. 2 in Brown as a single piece.
Miracle Fit Superproof Liner is the 0.5g proof formula
Back Gel Miracle Fit Superproof Liner is listed at 0.5g and appears under two close listing names on skinsli, Superproof and Super Proofreading, for the same 0.5g product.
High-tech Flat Liner uses a 1.2g flat tip
Back Gel High-tech Flat Liner is listed at 1.2g and uses a flat applicator tip, different from the round-brush format of the other Back Gel liners.
Picking a brush or tip style
The base and Z liners use a standard liner brush, Long Brush extends that brush for more reach, and the High-tech liner swaps in a flat tip, so tip style is one way to narrow the choice.
Choosing between Long Brush Black and Brown
No. 1 Black ships as a 3-piece pack while No. 2 Brown is a single piece, so pack size differs by shade in this particular listing pair.
