The cup is made of pure titanium both inside and out, featuring properties of freshness preservation, bacteria inhibition, light weight, no flavor transfer, and easy cleaning. It is lightweight yet durable, rust-proof, corrosion-resistant, and acid-alkali resistant—suitable for holding any beverage without heavy metal leaching or corrosion. Its lightweight body weighs only about one-third of a stainless steel cup while maintaining the same strength.With a tight, seamless seal, it remains leak-proof even when rotated or inverted, ensuring worry-free portability. The silent silicone pad at the bottom is anti-slip and wear-resistant, allowing the cup to be placed quietly without noise.This cup transforms Master Zhu Bingren’s famous work Burning Sunflowers from a museum exhibit into a daily-use cup, enabling users to experience artistic aesthetics while drinking tea daily and endowing the product with the label of "a portable work of art." Deeply integrating national intangible cultural heritage copper carving techniques, it features three-dimensional engravings of palace-level art on the titanium cup surface. The product combines collection value and status symbolism, aligning with the concept of "Zhu Bingren’s works for distinguished figures."
