Serious Tissues is the UK's first certified carbon-neutral toilet paper. Products are made and manufactured in the UK from 100% FSC approved recycled paper. They are bleach-free and there is zero plastic in the packaging and a tree is planted for every pack sold. Interfold Hand towels allow for larger sheet size. The individual towels fully unfold ready for use as they are dispensed, maximum drying capacity ensures hands are properly dried. As you pull a towel down, it automatically unfolds bringing down another towel ready for the next user. Very economical as they are slightly smaller than Z-fold or C-Fold. This is our best selling system, particularly for Nursery Schools, colleges and hospitals.
