An ideal device for trapping flies, wasps, spiders, etc.
You simply place the transparent pyramid over the insect on a wall or window, rotate it 180° (causing a door to slide closed), carry the insect outside, rotate the pyramid 180° again (letting the door slide open) and release the captive.
No muss, no fuss, and no big welts. 16" long in total.
Made in England by environmentally sensitive people.
