Love making your own blends? These CLANRIZA roll-on bottles are perfect for DIY essential oils, perfumes, serums, and massage oils. Each set comes with 12 clear glass bottles (1 oz / 30 ml each), complete with smooth-rolling ball applicators and tight-sealing caps. Why glass? Because essential oils can eat through plastic – glass keeps your blends pure and potent. The clear design lets you see exactly what’s inside and how much is left, which is super handy for colored oils or custom perfume mixes. The rollers apply just the right amount without waste or mess, and the caps are seriously leak-proof – toss one in your bag or luggage without worry. Great for small business owners, crafters, or anyone who likes to personalize their skincare and aromatherapy. Whether you’re gifting blends, selling homemade products, or just organizing your own collection, this 12-pack is a total game-changer. Easy to fill, easy to use, and they look professional too.
