4 Guardhouse double row boxes for round Airtite capsules, very lightly used in the following sizes: Small - fits A size Airtites Medium - fits T size Airtites Large - fits I size Airtites Extra Large - fits H size Airtites I ended up never using these boxes and would like to find someone who will put them to good use. These cost $9 - $10 each new, but I'd be happy to let them all go for $20 + $3 shipping (i.e., box, postal costs), or best offer. Thank you!
