Ever struggle to find an LED strip that's just the right fit for your odd decorating project? Me either. But it's good to know that there's such a thing as these flexible light strips which can be cut to size.
The strips are less than a millimeter thick and available in red, green, blue, and white. Pricing varies based on quantity. [LightForm via Dornob]
