Not so itsy, not so bitsy. This Black Spider Crasher Window Cling is not climbing up any water spout, but passing through your window. Measuring 30-inches in length, this hairy Halloween window decoration is a fantastic piece for scaring anyone who suffers from arachnophobia. The black spider is made of 2 halves. Each half features a suction cup on the inside to stick onto a window. When lined up, the window cling decoration gives the illusion a big, hairy spider has broken through the window.
