Product description

Colour‑coded glazing packers provide fast, accurate shimming for windows, doors, flooring, furniture and construction projects. Each thickness uses a dedicated UK industry colour for quick identification. Made from strong, non‑compressible polypropylene, these packers offer stable, long‑lasting support without crushing under load. Their 28×100 mm size is the glazing standard for UPVC windows, door frames, joinery, and general levelling work. Choose the 100‑Pack Mixed (1–6 mm) to start any job, then top up with 200 and 500 single‑size packs in the most used thicknesses: 2 mm, 3 mm and 5 mm. Trusted by installers, builders, carpenters and DIY users wanting consistent, accurate and professional results.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
