its a pretty basic pen that plays my word, the chip is just a normal sized bump n go one and it uses 1 battery inserted via the top by removing the little cap on top. surprised that the chip works with just 1 battery though. NO: 1886 12 Company: Baing Fun
repairs: needed to clean corrosion, the pen was extremley dirty, and the actual pen itself died, if you ever get one of these broken, dont even try to repair it, these are glued together and will NOT come apart easily. i actually had another that i tried to fix, but it got ruined from the repair. not all of these actually have a little cat ontop, they where pretty lazy and decided to give a nub to the bottom of the figures, put glue on them, and stick them in the screw holes so they wont fall off. my previous one did not have one but its really hard to tell which ones didnt include them via factory and which ones got torn off from the previous owners. however, there are photos of packaged ones that dont include figures ontop, so its been confirmed not all include them. bought from ebay australlia and arrived yesterday, i really like it. rarily 7/10 pretty easy to find on ebay and taobao. they are pretty cheap too.
