Here are details on the product straight from the creators:
Imagine being able to build around corners, on curved surfaces, or even onto the sides of that sailing ship you've just spent hours building. You forgot to engineer a point of attachment for that sweet dinosaur-smashing cannon? No problem. Snip a length of Nimuno Loops, stick it on the hull, mount your cannon and be on yarr way.Here is a video from the company.
Compatible with LEGO® Blocks, Mega Bloks, Kreo and most major toy building block systems. A whole new universe of possibilities when constructing with Nimuno Loops!
