I purchased this on Amazon one year ago. I put it away after playing with it a few times, so I'm selling it now. I have confirmed that it works. I wiped it down overall with a disinfectant wipe. There is a stain-like mark in the middle of the white part of the drum (Image 3). Please be aware that this is a used item, so those who are sensitive to such things should take caution. Instant purchase is OK. Thank you.
