This package of adhesive ephemera, Pipes and Mechanism, is part of the Songs Of The Sea Collection designed by Antonis Tzanidakis and Farrel Tailor for Stamperia. This package includes 31 pieces of ephemera including steampunk gears, pipes, a telescope, a candle, and more. These pieces can be used for cards, scrapbook pages, tags, journals, and other paper crafting projects. These pieces are printed on 300 gsm paper which is heavyweight paper. Note: These are self-adhesive pieces and per the manufacturer, for an easy way to peel off the backing, do not use your fingernail, rather use the soft pad of your finger and rub the edge two or three times or until the backing starts to separate and then it will peel away easily.
