In general: All grips are bad and you will need to change them. 

Strings may be loose ... these are vintage old. Most have scratches. If there's a vibrator, that's old too.

If you want combined shipping; wait for me to fix the invoice. Up to 3 rackets can fit into 1 box. Combined shipping if you WAIT will be as follows (USA) 1st shipping charged like the listing then + $5 for the 2nd and + $5 for the 3rd. If you buy 4 rackets the 4th one restarts at the highest shipping again. ---> If you end up paying full price on shipping on multiples there will be NO partial refund!
