Want to let others know to keep out? Well then just pick up this USB Construction Site, I’m sure that’ll teach them. The best part about this light up nonsense is that it’s travel size. No matter where you’re headed, this will always easily fit into your laptop bag. What more could you possibly ask for?! Sadly these aren’t being sold in the UK or the US. No, this one gets filed under Foolish Gadget’s Made in Japan section of the site. That means it’s going to be a little more difficult to get it outside of Japan. However, if you do manage, these will be released February 21st for about $20.
