Sooo I didn’t devote a lot of time to trying it, but I teach a toddler class and I got it to use it there. Couldn’t figure it out right away (keep your eyes on the toddlers at all times!) so I got just regular tape and have been using that instead of this... and then a small piece of plastic came off and we never had the time to figure out how to actually make it work, but if you translate one of the Japanese reviews it explained it decently, but I honestly haven’t touched the dispenser in months.
