Rainbow. Gold. Holographic. Metallic. These tumblers from Johnson Plastics Plus are unapologetically loud—and we LOVE that.

In today’s video we test their rainbow and gold holographic stainless tumblers, laser engrave them, show the results, talk about materials, cleanup, and whether they’re worth stocking for your shop or Etsy store. Spoiler: They photograph beautifully and customers will notice them on a shelf.
