Jewelry makers and dental pros - this wax wire set has you covered for all your spruing and mould-making needs. You get three bags with different diameters ranging from 0.8mm all the way up to 7.0mm, so you have the right size for any project. The blue round wax lines are 16cm long and come in varying weights per bag depending on the thickness. This stuff is seriously reliable - it's been used by jewelers and dental professionals for over 20 years because it performs consistently. The texture is uniform, it melts easily, and most importantly, it burns out cleanly without leaving residue that could ruin your castings. Perfect for creating sprues on jewelry pieces, making air vents in moulds, or any other wax work where you need precise, clean lines. The different sizes let you choose the appropriate thickness for your specific project - thinner for delicate pieces, thicker for larger castings. It's also great for hand art and other moulding applications beyond just jewelry and dental work. If you're into lost wax casting or any kind of mould making, having a variety of wax wire sizes on hand makes the process so much smoother and more professional. This three-bag set gives you excellent value and versatility for all your wax working needs.
