3 piece set. Channel 5,75x0,25inch, Pull tab guide 5,75x1,25inch, Slider tab 5,75x0,75inch. The U guide provides for a snug fit, eliminating the wiggle some slider designs allow for while streamlining the slide and creating a slimmer profile than even the thinnest foam tape. Position your channel on your card panel to accommodate the desired placement of the die cut, adhere the guide on the back of the panel centered around the channel, and insert the slider tab from the back, adhering the die cut from the front with a Spin and Slide Disc to create the movement. This ingenious set will coordinate with any number of products in your stash already and is a particularly great complement to the Typewriter and Dessert on Display die sets.
