OUGD201- What is Good Concept Crit

My concept crit today really helped to finalise my idea and for me to move forward with it... my group thought the idea was really strong and that it sounded fun, unusual and liked the interactive nature of this lasting souvenir.
i need to make clear what my range is... is it the range of products i am packaging within the pack or should i package the range of singles to make a collectors pack?
