These clear round acrylic tubes are made from PMMA (polymethyl methacrylate), the same material used in optical-grade displays, giving you a glass-like transparency without the weight or fragility of actual glass. DIYers, crafters, and small-batch candle makers who need a reliable, consistent hollow tube will find these a practical go-to.\u003c\/p\u003e\n    \u003cp\u003eEach tube measures 250mm (≈9.8\") in length with an outer diameter (OD) ranging from 8mm (≈5\/16\") to 20mm (≈25\/32\"), available in seven sizes. The gloss finish is smooth on the exterior and interior. Wall thickness varies by diameter — contact us to confirm before ordering if your project requires a specific inner diameter. Quantities are available in 1, 2, 5, 10, or 20 pieces per order.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include: clear acrylic candle molds for pillar and column candles, transparent display tubes for jewelry or small collectibles, lightweight structural spacers in model-making and robotics, and protective sleeves for LED strip lighting in craft and signage projects.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003eℹ️\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility Note:\u003c\/strong\u003e These tubes use metric OD sizing (8 mm – 20 mm).
