Create functional, geometric stationery and custom artisan gifts with our Square Pen Silicone Mold. Featuring a sharp, structured barrel profile that transitions to a tapered grip end, this mold lets you create sleek ballpoint pens that offer an ergonomic grip and resist rolling off flat surfaces. Made from high-grade, durable translucent silicone, the inner surface is polished smooth to yield a crystal-clear, glossy finish with easy demolding. Simply insert a standard ballpoint pen ink refill before pouring UV or epoxy resin mixed with dried petals, alcohol inks, mica powders, or foil flakes to craft unique, custom stationery pieces.
