And, if you can't find any labs in the Memphis area that will use care in opening the cartridges,
and return the '126 cartridges' and the 'backing paper' to you...Blue Moon will.
Just ask or tell them to do so.

Blue Moon is very accommodating to folks shooting odd formats...ie;
Mini 16, Minox, 110 & 126 cartridge, 620, 127, etc...
