The Clip Stand Version 1.5 were stands that could be purchased from GSC that offered a different way of displaying your Nendoroids that are designed to use a peg-in-the-back style stand.
Each stand came with a "base" piece (sturdy spring-loaded clip) with an attached arm and a peg of the same matching color. Originally they came with one peg for Nendoroids and one for Nendoroid Petites (you could swap out the peg depending on what figure you wanted to display).
The Version 1.5 was available to purchase in the following colors: crystal clear, dandelion (yellow), cerulean blue (to coordinate with Hatsune Miku), Mint, Pink, and White. Translucent Orange was only available as a limited edition item when preordering Nendoroids on the GSC website.
