Engineering Card Protection for Collectors and Distributors Across 35+ Countries
We are Foamgrid — a Dongguan-headquartered OEM/ODM manufacturer that has spent 13 years doing one thing well: turning raw TPU and PC into Toploaders, Magnetic Card Holders, PSA Bumper Guards and Graded Card Slabs that keep grading houses, TCG publishers and Amazon sellers running order after order.
Under One Roof
A TPU-First Manufacturer Built Around Real Collector Problems
Most card-protection suppliers sell standard part numbers. Foamgrid sells card safety. Our 6-strong engineering bench starts every project with a question — "What does a perfect Magnetic Holder feel like when a collector snaps it shut?" — then designs the tooling to deliver it, not the other way around.
From our 10,000+ sqm Gaobu plant we injection-mould, ultrasonic-weld, print and pack every unit in-house. There is no trader between you and the production line; every Shore-A hardness reading, every clarity test, every drop test is signed off by people on our payroll. That is the only way we know how to back a 12-month quality warranty without flinching.
Six Workshops, One Continuous Production Line
TPU pellets enter at the north dock and leave as fully packed, FBA-ready card protection at the south dock. Take a walk through the six workshops we run every working day.

13 Years of Building, Exporting and Innovating
From a 3-machine workshop in Gaobu to a 10,000+ sqm vertically-integrated plant supplying 35+ countries — here are the inflection points along the way.
Started our foreign-trade journey in Hong Kong. Met our first customer — Mr Hande — on the road; a partnership that continues to this day and became the seed of our export business.
Set up manufacturing operations in Dongguan under the Hande name. Landed our first ¥1M order within the very first year.
Hit ¥10M in the first full year of manufacturing operations. Celebrated the milestone with a full-team seaside retreat.
First-time exhibitor at Shanghai International Fair. Won 10 new customers on the show floor. Our first salesperson's annual salary crossed ¥300K.
Went omnichannel — joined Alibaba International Station, listed on Made-in-China.com, and started attending the Canton Fair every season.
Quickly pivoted to epidemic-prevention supplies during the pandemic. Annual sales pushed past ¥20M against a downturn that closed many competitors.
Sales team grew past 16 people. Refined organisational structure with dedicated OEM, retail and grading-house desks. Wrapped the year with a villa hot-spring retreat.
Cumulative sales since founding crossed ¥100 million. Established Foamgrid — our dedicated brand for trading-card protection products.
Opened Hande's second branch to relieve production capacity. Served 300+ new and returning customers over the year.
① Marketing strategy upgrade · ② Localised overseas sales · ③ IT-enabled operations · ④ Diversified product development.
Launching cardholderpro.com — our new global B2B storefront. US / UK / DE / FR / JP forward-stock warehouses coming online. Expanding PSA Slab Protector and Bumper Guard lines to cover all five top grading houses.
Feel the Quality Before You Place Your Order
Most factories require 500–1,000 units to start. We say one. Whether you’re validating a new SKU idea, running a Kickstarter, or preparing a PSA/CGC submission, we ship a functional sample within 7 days so you can iterate fast — without inventory risk.
An 8-Stage Quality Control Routine Across Every Order
A cracked slab on a graded PSA 10 is unforgivable. Our QC team intercepts defects at 8 separate checkpoints — long before a Toploader ever sees a container.
Container-Optimised Packing & Door-to-Door Logistics
Damage in transit shouldn't delay your Amazon launch. If anything arrives broken, we ship replacements first — claims come after. Your restock date never waits on our paperwork.
From Order to Shipping in 15 Days
A transparent, milestone-driven workflow. You know exactly what happens on which day — with weekly progress photos in your inbox.
After-Sales Built for a Long Partnership
A 30% repeat-order rate is not an accident. Treat your supplier the way you would treat your accountant — by what they do 12 months after the invoice clears.
- Free replacement of any component failing under normal use within 12 months
- Anti-yellowing warranty on UV-grade TPU parts kept indoors
- Design consultation included free across entire warranty period
- Spare tooling retained for min. 5 years from your last order
