One NO vote here.
Not because I care for the environment (but what the hell, a few less plastic seal ain't going to save the planet any way..., let's burn to hell with our Yammies...), but there is something about unsealing a new toy that make me feel I have just devalued a perfect toy, and I don't mean monetary value alone. If there is no seal, as long as I look after my toy well, it is always a perfect toy for me. For the same reasons I hate toy accessories that are attached to the plastic carcass.
