THANK YOU! This is why i posted rather than just ordering...so these won't melt in the pressure cooker? I did a little reading and found the PET ones are not autoclavable. But these are polypro. Any issue with the snap caps instead of screw on caps? don't want them to snap open and spill...
500 for $23 is much better than $100 for 240 of the glass ones!
