I recently got these stickers in the holographic material and they didn't print as well as I'd hoped (no shade to the holographic stickers - my design just wasn't the right fit for them with all of the purples and subtle details they had). I contacted Sticker Mule and they were AMAZING in consulting with my order, and offering to reprint them in glitter. I just got my stickers and I LOVE them, and am so grateful for the fantastic customer service! 

Fantastic Customer Service!
