# Rehearsal

What the rehearsal does is to provide more accurate measurements of weight and dimension of your parcel, allowing you to use a specific shipping line

You need this because, sometimes, the initial weight + volume calculated by PandaBuy is an estimate, if your weight is just about too high for a specific shipping line, then a rehearsal might be able to let you use that specific line

Only in that case, then, rehearsal would help you use that specific line.
