Is working for a company that sells household appliances, which includes selling sex toys, permissible or forbidden?

Selling dolls, sexual organs, and similar "sex toys" is unlawful (haram), and it is impermissible to engage in their sale or assist in it. However, if it is possible to avoid selling these prohibited items, then your work is permissible (mubah) and your earnings from it are lawful (halal).
