Hi Everyone!
Can anyone share a source for clear plastic/acrylic
display cases that is reasonably-priced and takes
PayPal? I'm looking for something bigger than the
gem jars used for micromounts, but smaller than the
typical large cases used for some collectibles like
model cars. What would be ideal is a large gem jar
with a diameter of about 3 inches and a height/depth
of 3 inches, give or take.
I've looked all over the web, and I can only find
overpriced offerings or sites that don't take PayPal.
I have to use PayPal to keep my collecting seperate
from the household money and avoid the wrath of the
CFO. ;)
Thanks in advance!
