ZGS Glass Workshop Unveils the Bulb Cup: A Playful, Customizable Addition to Any Tabletop

When ZGS Glass set out to design a new drinking cup, we asked a simple question: why should glassware feel ordinary? The result is the Bulb Cup, a soda lime glass straw tumbler shaped like a light-bulb moment. Designed for cafés, caterers, gift-box brands and any tableware distributor tired of “just another jar,” the bulb cup is now rolling off our production line in minimum runs of 500 pcs per design-ready for color sprays, electro-plating, private-label sleeves and full drop-shipping support.

From Sketch to Soda Lime Glass: How the Bulb Cup Was Born

Every glassware manufacturer keeps a library of silhouettes; we pulled the classic Edison outline and resized it to 450 ml, keeping the neck wide enough for easy cleaning yet narrow enough for standard paper or glass straws. The mold is machined in-house, so wall thickness stays uniform at 1.8 mm—light in the hand, tough enough for commercial dishwashers. Because we work only with food-grade soda lime glass, the cup stays crystal clear after 2 000 wash cycles, a must for any tabletop professional who has seen foggy drinking cup stacks ruin an Instagram shot.

Customization Without the Headache: Color, Coating, Carton

Once the transparent bulb cup is annealed and inspected, the real fun starts. Our spray booth can apply Pantone-matched matte or gloss color in single-day turns; electro-plating adds mirror gold, rose or gun-metal finishes that dress up the glassware for premium tableware sets. Need a kraft gift box with debossed logo, EVA insert and front window? We design, fit and drop-test it before a single drinking cup leaves the plant. Minimum order for custom packaging is still 500 pcs, so even mid-size café chains can compete with big-box tabletop brands without tying up cash in ten-thousand-unit launches.

B2B Friendly: One-Stop Quote, Run, Pack, Ship

As a glassware manufacturer that started in blown tableware and now ships forty-foot containers weekly, we know the pain of juggling vendors. One e-mail gets you a same-day quote that includes decoration, packaging, pallet specs and door-to-door freight to Long Beach or Rotterdam. Each bulb cup is sleeved in food-safe PE, divided by corrugated inserts, then master-packed 48 pcs to a carton—no clinks, no breakage, no hidden freight class surprises. After delivery, our after-sales team tracks defects down to the mold number; if a single drinking cup cracks in transit, we credit or replace on the next order, no photo circus required.

Why Tabletop Buyers Are Swapping Mason Jars for Bulb Cups

Mason jars had a decade, but their threaded necks trap pulp, seeds and boba. The smooth, rounded shoulder of a bulb cup rinses in three seconds, cutting bar-back labor at peak service. Because the silhouette photographs like a mood board icon, beverage brands see higher social engagement without paying influencers. Finally, soda lime glass is 100 % recyclable; when the trend fades, the material lives on, letting every tableware buyer hit sustainability targets without switching to costly borosilicate lines.
