Features: Gag Gifts for Adults: It includes multiple sounds, beeps and more, very suitable for pranking friends, colleagues or partners. (Used much better in a quiet environment.) Long-lasting Battery: Our sound box will not die after a few days, the battery can easily support it continuously for several months. Easy to Hide: This super small beeping device can be easily hidden in most places. It is light enough that tape or magnets can hold it. Use them together or separately to drive them crazy. Hard to Locate: It's hard to pinpoint where the sound is coming from, due to random chirping intervals of about 3-20 minutes, before it draws power. Just turn it on, choose one of the available sound options and hide it. The best part is that it keeps making noise as long as it seems to work well as a prank. Please note: 1. The actual color may differ slightly from the image due to different lighting effects. 2. Please allow 1-3 cm deviation due to manual measurement. Description: Size: 8x11cm Package list: 1/2/5pcs Toys
