Although some of the merchandise was literally plastic, we featured items made out of any number of different materials.

Prior to the engaging profile in west3rdstreet.com, the innovative trajectory of Carla Denker and PlasticaStore.com had already captured the attention of prominent publications, each one spotlighting the unique allure and creative vision of the boutique. The acclaim goes back to features in Daily Candy in 2013, TimeOut Los Angeles in 2012, and stretched globally with Allure Korea in 2011. Esteemed columns in LA Times in 2010 and thoughtful pieces in Sunset Magazine in 2009 highlighted the boutique’s distinctive character, while Domino Magazine in 2008 celebrated its design-forward ethos. This press recognition dates back to the earliest days of Plastica, with citations going back as far as 1997, each telling a part of the Plastica story.

After an illustrious run, Plastica transitioned from the tangible to the intangible. While our physical presence concluded in December 2017, our essence endures. Plastica Store has been reborn as a digital haven, continuing to serve a community of discerning thinkers and seekers. Our new mission transcends physical boundaries to embrace a world that is increasingly seeking knowledge and depth.
