Common terms for unopened pack collectors, from cello and wax to crimping and slabs.
What to check
Match the format first: wax, cello, foil, rack, blister, slab or sealed box.
Check the seals and wrapper tension before believing the headline description.
Use sold listings to understand actual demand, not just asking prices.
Preserve packaging condition because small dents, tears or slab damage can change buyer interest.
