This new armbinder with mittens are made by Sweel Honi.
They are made for Maitreya and Bento hands and come with a colour hud for each part.
I tried several handanimations from the Maitreya menu and they all work.
She also integrated struggle movements in the armbinder, to give it a realistic idea.
The menu also gives a choice for latex and transparent (wearing transparent now).
By touching an invisible part at the right upper arm, you get the RLV menu to lock the armbinder and some more options.
