I didn't find another thread that mentions these so I thought I'd post about them.
BCW has a new type of storage box.
I ordered five of these. I only planned to order three but ordering two more got me free shipping and the two extra bins were cheaper than the shipping. They arrived yesterday. They are about as solid as milk/storage crates and feel like they are made of the same material, only slicker and glossier. They arrive flat in in pieces, requiring assembly with instructions provided on their site. They were a little difficult to assemble in that the pieces fit incredibly tightly. The rep in the video either has super human hands or the one he put together didn't fit nearly as tightly as mine. I used a rubber mallet to put the final taps on all of the parts. Once in place, I can't imagine that they will ever come apart through any normal wear and tear. I love these boxes. I love that they include dividers to hold books up in less than full boxes. I'll use them for a show in February and report more then. I'm not a dealer, just an attendee so I won't be able to attest to how they hold up to multitudes of browsing fans. My only reservation is the price. A milk crate can be had for $3-$7 and while there is certainly more material used in these bins as well as having more involved construction (at the manufacturing level), I can't imagine that these warrant three times the price. I need a minimum of 160 to get started in putting my entire collection into them. I'm thinking of ordering five per month unless I can score some kind of bulk deal.
