My examples of the Olicamp/Liberty Mountain Aluminum Matchbox have arrived.
The hanger card on the package does not mention Oilcamp. It reads "Liberty Mountain, Salt Lake City, Utah"
The description on the hanger card is: "Rugged - Milled from a solid piece of aluminum for exceptional strength."
The device is made from three pieces of aluminum. The body is machined from 2mm aluminum tube stock. The bottom is pressed on. The screw top is machined from an aluminum slug.
A lanyard ring is provided.
The diameter of the cavity is 13/16" (20 mm).
The depth of the cavity is 2 3/16" (55mm). Current Diamond "strike-anywhere" matches are 2 5/16" (58 mm). (Old Ohio Blue Tips are 2 7/16, or 61.5 mm.) Screwing the cap closed on the Diamond matches crushes the striking tips. A post I recently found at the other forum reports that attempting to close the cap on a full load of strike-anywhere matches forced the bottom off the matchbox.
A less than 1 mm O-ring is provided to seal the cap-body contact. There is no detent, so the O-ring moves up when the cap is removed.
The body and cap seem sturdy enough. The bottom would not be subjected to much stress if full-length matches are not used.
Placing a disk of innertube rubber or equiv. in the cap would produce a good matchsafe for matches smaller than 53mm.
It could also be used for other items/materials one wishes to keep dry. Inferior products are sold at much higher prices.
On examination of the black example, this is the same product sold for up to $10.00 at other vendors. Mine came for less than a third of that from JNKPRODUCTS.COM, which may, in fact, be Liberty Mountain based on the UPS tag.
I have e-mailed Liberty Mountain asking about the depth of the cavity and why the prioduct is claimed to be made of "a solid piece of aluminum."
