This is an original 3D puzzle. It's structured so you combine multiple blocks to complete a cube or various other shapes. You can train your spatial reasoning skills while playing, or display it as an interior object. This product is handmade (3D printed) and produced one by one. Therefore, please understand the following points before purchasing: ○ Layer lines, minor streaks, and warping may be visible. ○ There may be individual differences and slight looseness/tightness in the fit of the pieces. ○ Tight areas can be adjusted by lightly sanding. ○ Please refrain from purchasing if you require the precision tolerances of an industrial product. Production will basically be based on a random configuration, but if you have any requests, please consult us in the comments with the following details: ○ Desired color (e.g., white, black, transparent, two-color configuration, etc.) ○ Size/number of blocks (e.g., 3x3x3, 4x4x4, etc.) #SomaCube #3DPuzzle #EducationalToy #3DPrint #Handmade #BrainTraining #Interior
