About this Product
This file is for extensions to turn an Eastsheen (42mm) mini 2x2 into the shape of a heptagonal prism.
So for the complete puzzle you will need to purchase these extensions, and super glue them on to a slightly sanded Eastsheen mini 2x2.
After doing so you turn the top or bottom layer a single notch, and then sticker it with stickers from Oliver Nagy's shop. Use the pictures for a reference if needed.
Contact me if you would prefer to get a fully assembled and stickered version for 45USD.
