Log strips from Petror.se, made from Rite In The Rain® paper, which makes them both waterproof and highly durable.
 

 
This log strip has a width of 66 mm and space for 108 logs. Log strips in this size are best suited for larger caches, but can also be rolled up and placed in e.g. petlings.
 

 
The log strips are first printed using a laser printer and then cut with a professional paper cutter, making them straight and neat. However, minor variations in dimensions may occur.
