I have ten shipping boxes for guitars in great condition.
Approximate size for each varies, but the standard size is around 51" x 20" x 9" each.
These boxes are great for shipping electric solid body guitars, or semi hollow… acoustic guitars can fit in a couple of the larger ones…
These boxes cost $25 if you bought them at UPS…
Mine were shipped to me by Gibson, PRS, or other manufacturers…
$12 for one, $25 for three
$35 for five boxes, $60 for all 15
It would be a shame to slice the taped boxes so that they would fit in your car, but… That’s up to you… If you want to leave them in their constructed form, bring your SUV… Ha ha
