Spare TE Probe Storage

I have a spare TE prove (ESA-Systems type UN triple probe) that I
want to store safely in the trailer. Where it won't get damaged. Has
anybody found the ideal container or way to store these? I want to
keep it safe from physical damage, dust and tiny insects etc. This is
not the probe I routinely fly with, that just lives in the cockpit
when the glider is in its trailer. This is a spare part. Why I think
it is necessary to carry a spare probe in the trailer is not a story
I'm going to get into :-(
