Small jars

If anyone buys food, jams, cooking ingredients in 90ml glass jars, please could they save the empty ones for me? I like to take my home-made jams and chutneys as gifts when I travel, but almost always fly with just hand baggage. Anything over 90ml seems to be mistaken for over 100ml, and gets confiscated, so now I play it safe. Bart's fresh spice pastes and ready chopped garlic or chilli often come in these jars. Thanks in advance.
