Mini Plastic Spiders - 3cm (10pk)

The legs are slightly flexible, which makes them look creepier when you set them on a table. I used them as a prank on my coworker and got a perfect scream.

They're surprisingly detailed for their size—the legs are even a little textured. I put a few in a friend's desk drawer and got a genuine scream, which was totally worth the price. Just keep the bag away from toddlers, as the warning says.

Exactly 3cm across, so they’re small enough to hide in a drawer handle or under a napkin without looking obvious. I’ve already used a few for a prank on my brother, and the plastic feels sturdy enough that they won’t snap in half on the first scare.
