They look so good, don't they? The mittens feature full RLV support with 3-level touch-block, animated padlocks which close when locked and an extensive appearance system with shine options (gives a great latex-look) and custom tints.
The deluxe version has also - additionally to the regular leather look - unique and cool tintable texture options. Some of them are definitely steampunk compatible too! :-)
You can get them at Emma's store Sunshine Technology
