Being thinner than 40 micron cello it is slightly more economical and is used for wrapping flowers and gifts that do not need the extra thickness. 30 micron clear cello is also available on a roll in a number of widths. 500 sheets are easier to manage than 1000 sheet packs.

If you intend to use this product to wrap valuable/rare fine art, we do recommend that you consult with a fine art specialist before use.
