NOTE8 JUNE 2026 — OUHAI — HENRY, EYEFIY
Two rivets, not one
Three metal logos fell off a 600-unit order. The cause was one rivet where the bend needs two — a few cents of savings against a four-figure claim.

A French brand wrote to us about an order of 600 frames. Three logos had come off the temple end pieces.
Three out of 600 is 0.5%. It is also three of their customers holding a frame with a bare patch where the brand used to be.
We traced it. A metal logo on an end piece — especially where the end piece bends — needs two rivets. One into the top face, one into the front. This batch carried one rivet per logo.
One rivet holds through assembly. It holds through packing. It lets go in a pocket, three months later, on someone else’s continent.
The fix is not clever. Two rivets instead of one. Under the plate, a dab of UHU or crystal glue before the logo is pressed home — the squeeze-out cleans off before the water-film stage, so nothing shows. A rivet costs a few cents.
The claim did not cost a few cents. Replacement pieces, shipping, and a brand explaining itself to three of its own customers.
Why does the single rivet exist at all? Cost shaving in a place no drawing calls out. Shenzhen shops set two rivets on a bent end piece as the default. In Wenzhou you will still find one — a few cents saved on a part that carries the customer’s name.
Our spec sheets now carry the rule in writing: metal logo on a bend gets two rivets plus adhesive. No exceptions. Checked at IPQC, not at the claim stage.
