The appliances also come with 'whiskers,' adhesive, and directions on how to apply. Rick also has blank appliances, as well as precoloring and flocking on the appliances, for an extra fee.

These people sell a very comfortable line of foam latex facial appliances that can be worn many times, for many hours. They go for $50, with a full-head appliance going for about $140. You do not just get the appliance, you also get a booklet telling how to apply it, what to use, and then some, which is VERY informative. Some costume shops may sell these, though a limited selection. According to the site, e-mail is the quickest way to get an answer, as their phone lines are very busy.
