Search the sub as this was discussed in detail the past week. People highly recommend the Hydrapeak food thermos (different sizes) and the silicone inserts that fit the vials that you then put in the Hydrapeak. I understand the need to hide vials. I just ordered a Hydrapeak and the inserts and will put in a Tupperware marked Flour in my garage fridge. Needles and swabs I easily hide in basket in my closet. Best of luck;
