By placing this simple placard near the center of your laboratory you can simply and swiftly ensure the participation (if not the consent) of those occasional visitors who represent such a rich trove of experimental subjects. We recommend its use on a t-shirt. T-shirts of this design have proved effective in nearly every case, be the subject a deliveryperson, a home improvement contractor, a relative, or (as in one remarkable case) a baboon.
Soft and comfortable, durable and thick, this 100% cotton t-shirt is made from 5.29oz fabric in a variety of colors and sizes.
The shirt is double stitched and has reinforced seams at shoulder, sleeve, collar and waist. Fairly produced, certified and triple audited, these imported shirts are printed in the USA.
