5133 different caps from 180 countries

Storage system

I keep my caps glued (with double sided duct tape) on ten wooden boards. Each board measures 60cm x 40cm and can hold up to 228 bottle caps.
The caps are stored in chronological order, considering the date I added them to my collection, so Board 1 holds the first caps I've collected.
