The Mini is ideal for a spare or travel pair of tranquileyes. The name 'Mini' refers to the size of the canister. The goggle is standard size and features our standard foam with fabric. Like all other tranquileyes goggles it can be used to create complete darkness to help you sleep or with warm water to help relieve dry eyes and cold water to help reduce puffiness around the eyes. The Mini includes a mini stainless steel travel canister, one pair of tranquileyes & a manual. Made in the USA.
