Perfect Fit Solution for Glass Candle Jars with Wooden Lids – Sunny Glassware Delivers in One Go

"Three suppliers failed to fix the perfect fit issue of glass candle jars with wooden lids, but Sunny Glassware nailed it in one go!" — Genuine feedback from the Procurement Director of a North American gift brand

The story started two months ago. A North American client specializing in the holiday gift market planned to launch a custom set of glass candle jars with wooden lids, primarily for Christmas gift procurement. Their previous suppliers had never managed to solve the problem of precise fit between the glass jars and wooden lids: either the lids fit loosely, or they were so tight that the edges of the glass jars cracked. With the delivery window drawing near, the client urgently searched for "custom glass candle jar with wooden lid manufacturer" on Google and found Sunny Glassware, a company with over 20 years of experience in the glassware industry.

The client came with clear order requirements, along with core challenges to be addressed: the diameter of the glass candle jars must precisely match the wooden lids, with the tolerance controlled within ±0.1mm; the wooden lids need waterproof and anti-deformation treatment to prevent damage from contact with candle wax; the products must comply with North American FDA food contact safety standards; and the first batch of 100,000 sets must be delivered within 35 days, which is 10 days shorter than the industry's custom production cycle.

Upon receiving the inquiry, Sunny Glassware R&D and production teams immediately set up a special task force and provided a targeted solution within 12 hours. To tackle the precise fit problem between the glass jars and wooden lids, we leveraged our 20 years of accumulated precision molding technology. By using CNC for precision mold cutting, we strictly controlled the diameter tolerance of the glass jars to ±0.08mm. Meanwhile, we customized a special waterproof coating for the wooden lids, which underwent 5 rounds of temperature and oil resistance tests to ensure no deformation even after long-term contact with candle wax.

Full-process transparent communication maximized cooperation efficiency: we updated the client with daily progress reports and on-site videos, covering everything from glass jar sample making and wooden lid fit testing to mass production progress. To meet North American customs clearance requirements, we prepared a complete set of compliance documents in advance, including FDA certification and raw material inspection reports. In the end, Sunny Glassware not only delivered 100,000 sets of glass candle jars with wooden lids in just 32 days, but also achieved a 100% pass rate in the spot check of fitting accuracy, with waterproof performance far exceeding the client's expectations.

Once launched, this set of glass candle jars with wooden lids quickly became a bestseller in the North American Christmas gift market. The client subsequently placed a repeat order for an additional 200,000 sets and officially designated Sunny Glassware as its core strategic supplier.

With over 20 years of dedicated focus on the glassware sector, Sunny Glassware products have been exported to more than 20 countries and regions. From custom glass candle jars to various types of glassware, we always use craftsmanship to solve every production challenge and rely on strength to earn long-term trust from global customers.
