• Shape Shifters were designed to provide a stable yet adjustable structure for beautiful, uplifted posing on any surface.
• These pieces don’t rock, roll, or create lumps and bumps that are difficult to hide (be sure to use a lot of layers over the top of them!). Stack them, shift them, or build them up - every piece is made to adjust easily, whether you’re making tiny tweaks or big changes.
• This set includes a head piece, foot piece, and four lifters. You will also receive a digital use guide showing how to set up the pieces for various poses and many tips and tricks for making the most of your Shape Shifters.
