All International 420 sails measured on or after 1 March 2005 require sail stickers. All orders must be submitted on the official Sail Sticker Order Form. Sail Stickers are available in packs of 10 and cost €13 each, plus postage and packing.

The income from sail buttons is used to fund the 420 Class Development Programmes around the world.
