I think the Devine toy box looks a little more suspicious. My fiancee and I will probably end up with either the original ToiBocks or the ToiTissue. I really wish the ToiTissue had a lock of some kind!

Personally I'd recommend the bigger Devine *toychest* which locks but it's out of stock, it's not OVERLY discreet but it isn't overly naughty looking either. you might get a question about it but not much more than that except from really really nosy people.

Besides that I'd suggest buying one or more of the Lockable Toy Boxes, they really appear to be something you could carry around in public with no questions asked except 'ooo, where'd you get that' maybe. they can be found here: link in multiple colors just like the toychest I previously mentioned

The Toibocks is a more pricey but discreet option though

A big gun safe. The kids will never be able to get a hold of your toys with them in a safe.
