perfect for homemade antibacterial spray so many uses [SEP] these were just what i needed to make my own alcohol antibacterial sprays after being unable to find lysol spray i resorted to mixing part rubbing alcohol to part water and adding to a spray bottle that ended up with a leak i ended up trying these and it made individual sized sprays that are perfect for on the go or putting one in every room if the house i use these to spray groceries down spray on cleaned countertops and faucets etc the plastic is thick and none have leaked the set even came with two cute little funnels to help add your own liquids there are so many uses for these and they are which is perfect for airline carry on bag requirements i am so glad i saw these now instead of having all of my antiseptic spray in one large bottle i have with the enclosed labels added in each car and room of the house
