love product please offer duplicate stickers and more than one return stck [SEP] had to buy this set to replace one defective pitotube in a set i bought previously too expensive to buy individually amazon would not give me a replacement for the one defective bottle out of a set they gave me a small discount on the defective set i needed the size of the defective one so i had to pay for three to get one the defect was in the cap it would not latch on and falls off the bottle otherwise i love pitotubes they never leak even when traveling in luggage compartment of a plane i wish the pack came with more than one return stick and duplicate product labels they are cheep and inexpensive and pitotubes does not sell replacements i found a work around i bought solid thin plastic beverage stirrers to use as return sticks they work like a charm even on small bottles
