HongXing Qingyi 500ml Dual-Steel Straw Tumbler | Factory Direct

The Qingyi 500ml is the fashion-forward daily tumbler — the same 304+316# dual-steel construction as the premium thermos segment, in a compact 500ml format with a minimalist matte finish that carries no text, no logos, no branding on the body. The 316# inner wall resists coffee, citrus, and fruit infusion corrosion better than standard 304#; the 304# outer provides the durable matte shell.

The flip lid integrates a transparent drinking window and a built-in silicone straw — the window shows liquid level without opening, the straw stays attached to the lid assembly with no separate parts to lose. The vacuum double-wall keeps hot drinks above 55°C for approximately 4 hours and cold below 12°C for approximately 6 hours — the daily-commute thermal window.

Three matte colourways — Yellow, Red, Green — are fingerprint-resistant and colour-stable. The 500ml capacity fits car cup holders, desk corners, and handbag side pockets — the standard personal tumbler size for commuting and office use.

For wholesale buyers, the Qingyi targets women's lifestyle retail, boutique gifting, and premium office supply channels — where the 316# inner story and minimalist matte finish differentiate it from standard 304# competition at a premium price point.
