In response to Joyce Brite's inquiry about rubber bands, I can say that
Precision Music Rolls uses Plymouth Premium Grade pure rubber bands.
We use No. 14 for single-tune rolls, and No. 16 for the medium
(non-jumbo) rolls.  My supplier told me these are the best available.

They are sold by the pound.  According to the supplier, there are about
3200 per pound for the No. 14 size.  They are of much higher quality
than the drug store or convenience store variety.

To meet Joyce's immediate requirements, I will be sending her (gratis)
about an ounce or so.  Joyce, please let us know if these are what you
need.

Best regards,
Dave Saul, Owner
