For the price, this is a nicely turned piece of brass! Doesn't patina or tarnish too fast. When it
does, a paste made from salt and vinegar will shine them up sparkly bright.
The lid not
necessarily fitting their other boxes is perhaps a minor limitation. For those of us who want to
switch between boxes "on the fly" this could present something of an issue. If you want to
multi-box, you may want to buy the Okorto set and ask Penguin to inspect that the lid fits all the
boxes correctly before they ship it to you. They're characteristically awesome for this type of
thing.
The dvd is rather abysmal and only serves to demonstrate rather weak/basic
handling. David Roth has great insights on his DVD Ultimate Coin Magic Vol 2. A lot of what is
offered there translates very well to the slot, boston and slot+boston combination boxes as well.
So consider that as well if you're thinking coin box work is for you!
Cheers!
