[Excellent Samples] Drinking Straw $300.00 [These are the ones to obtain.] 
Straws work about 60% of the time. Noticeable chewing of the straw improves the chances. Sugarless drinks also improve the chance of successful extraction. Allow to dry at room temperature and place up to 3 straws from the same person (per order) in a clean paper envelope.
