On display at Wonder Festival 2014 are TakaraTomy Arts Teenage Mutant Ninja Turtles figures. These little guys look very cool too. They stand about 5 cm (2-inches) tall and feature their signature weapons too.
They are priced at 300 ¥ (Yen), which converts to about $3 US. We can look for these to be released in May, but not sure which US online retailers will be carrying them. (Source: TNI)
