About this item 8oz Plastic Bottles with Caps: Our PET smoothie prep containers are 100% BPA-free. Unlike glass, our bottle is light-weight, shatter-proof, and freezer safe. We recommend throwing out our disposable bottles after use. If you plan to reuse our beverage containers, hand-wash well with warm water, soap, and a sponge brush. Our small bottles for drinks are not dishwasher safe. Tamper-Proof Top: Our 38mm lids have a security ring so you'll know if your drinking bottle with lid has been opened. To ensure our drink container is sealed, push down the cap until you hear an audible "click". Then, tightly screw on clockwise. Small Juice Box: Our little storage bottles for liquids are the perfect size for a mini fridge. Our clear drinking bottles are ideal for meal prep, lunch, orange and fruit juices, green smoothies, milk, soda, beet root shot, nutcracker, liquor, and other liquids. Personalize: Easily customize our 12 oz clear container at home by adding your own label, icon, or sticker. We suggest using a label size of 2.5" H x 1.5" W, or you can measure our juice containers to determine the best size to suit your needs. Great Value Pack: Our pack comes with 48 empty bottles for drinks and 48 black tops. Each container has a 8 ounce maximum capacity. Measures approximately 4.09” H x 2.35” Diameter Opening.
