These "preform" geocache tubes are the early stage of a 2 litre soda bottle. They are virtually indestructible, dishwasher safe, and they are clear so you can see everything inside. (All preforms have a very slight greyish tint). Caps are included, and each one comes with two Rite in the Rain log sheets.
Or, turn it into a kit with everything you need to make your own soda bottle tube cache. Caps are included, and each one comes with two Rite in the Rain log sheets, an official geocache sticker with Beaver dude on it, and a geocache pencil.
Each preform measures approx. 14cm tall, and each holds about 60 ml.
