I'm an adult with ADHD and have recently discovered various fidget toys to keep me from biting nails, chewing lips etc when I'm distracted and trying to think while working at computer, reading, watching tv etc. The mochi squishies I got in a variety pack of fidget toys were far and away my favorites, so I began ordering packages of just the squishies. This brand is by far my favorite.I got a 72-pack assortment from another seller and those are fine, but have a strong plastic odor and are sticky coming out of the package. They need to be washed and treated (more below) before I can really enjoy them. The 30-pack from this seller was similar to the ones in the 72 pack, but so far, several orders of the 16-pack have been different and much more satisfying out of the package. They smell nicer and are not sticky.A couple of notes for the complaints. No, individual squishies don't last that long. The paint wears off quickly with handling and narrow bits like ears and tails start to tear. They eventually fall apart. They aren't meant to be particularly long lived toys but are the equivalent of something you would get in a gumball machine egg or a happy meal toy. I can see how this would be disappointing for kids who want to play with the toys as characters but for fidget toy purposes, none of this bothers me much.They last longer if you do a little upkeep on them. As I handle them, they start to get sticky and I put them aside. When I've collected a pile of "sticky squishies" I give them a quick wash in a bowl of lukewarm water with a little dish soap, then rinse and dry. At this point they will be VERY sticky and not pleasant to fidget with at all. I put them in a sandwich bag with a spoonful of cornstarch, shake them til coated, shake and rub off most of the excess, and towel them off, and they are ready to go back into fidget rotation. Most of them last a few of these rotations before they start falling apart too much and are finished.While I definitely have favorite shapes/animals, I don't care that much about getting specific types. The 16-packs generally seem to have mostly the same types -- cats, rabbits, elephants, and some flat ones like penguins, clouds and stars -- in each package. The 30-pack has a wider variety but sometimes lower quality with some weirdly misshapen ones like a completely flattened turtle. Again, doesn't bother me but something to keep in mind if buying for kids who want characters.To sum up, these are not long lasting individually but collectively are an extremely satisfying fidget toy, and a little upkeep makes them last longer.
