Query: fun initially, but beware of dust it collects...

the wikki stix have a slightly sticky/waxy feel, and they're fun to play with and to make shapes out of. but if you want to make bigger structures, you're gonna need much more than this set.unfortunately, the stickiness makes this toy awful because unless you're able to use them in a completely sterile environment, with none of the sticks falling on the ground, your stix are gonna get covered with dust, hair, etc... basically, whatever debris is on the surface. over time, the stix become less sticky. and i don't care how clean you are, there's no way that you'll win the battle against dust and hair shed.since i can't wash off the dust particles and hair, these just became too gross to play with. also, they didn't adhere as well because of, well, extra particles stuck on the stix. they were fun initially, but i ended up throwing them away. i guess wikki stix would be fine if you thought of them as semi-disposable, but i prefer toys that will last.
