I use lego pieces to do small frames and use plastic to protect them (similar to Ikea frames plastic cover)
Have the complete figures on a larger one, similar to that one.
Asked on the Instagram post when the pic appeared but got no asnwer...
I have one bootleg dark turquoise head but can't say if this one is real lego or not...
The lavender minifigures are available, but not when you search "Ninjago".
Try searching "the island". The eleven Ninjago figures will show, including the lavender figures.
Hope it helps (lavender hips, only for Luna minifigure)
