These are adjustable inserts for IKEA Samla boxes in sizes 5, 11 and 22 litres. They allow you to create an adjustable network inside the boxes to better organise your items. They are divisible into halves and quarters for further customisation options. You can even engrave or emboss layer marks for better organisation. They are ideal for easy access and organisation of small parts and to create a system that best suits your needs.
