You can f ind BJ's persistence and attention to detail
in many areas other than in our celluloid frames, like P-501.
Here are our six details that only experts would recognize.
Caulking pins that are as iconic as the front studs are all handmade.
First, we punch out 3mm diameter circles from thin metal plates, and then braze them before punching out again into star-shape. Next, we put them in a “Gara” (special rotary drum) to polish them, and repeat this process four times. After punching out into circles, we put them into the “Ara-Gara” and “Tsuya-Gara,”and then braze and punch out into a star-shape before polishing them four times to make our stars shine brighter.
When it comes to productive efficiency, you might want to use Philips screws, but we use slotted screws intentionally.
These offer a simple beauty, and boast a sophisticated, yet minimal design. With machined-slotted screws, we can make them flush with the end piece. The screws and the end piece look like as if they are integrated as one and, thereby, make our glasses look better overall.
Right now, machined (not forged) slotted screws account for only 10% of all screws used in our industry due to the production cost. Yet, by remaining persistent to our concept and values, we believe that using them allows us to make our products perfect.
Typical nose pads that are flexible often slip away from their ideal positions.
Yet, BJ’s butterfly nose pads are designed to go through the fitting process, so they are perfectly suitable for you. Now, we have a 100% titanium model in our lineup that allows you to have a luxury feel.
BJ’s titanium temples are made by adopting a method called “swaging” to 5-6 mm pure titanium round wires.
Swaging is a special method to improve metal density, springiness, flexibility, stiffness, and intensity by hitting and elongating round wires. After swaging, we flatten and trim each section (e.g. drop-end) before pressing several times to further enhance and strengthen the temple’s characteristics. These processes will sustain the holding power of the temples.
BJ’s product will lower your daily stress.
If both of your end pieces use a single screw fastened from the same side, one of the screws will tend to loosen when you try on your frames because this always adds some tension in the same direction. Yet, with BJ’s products, one end piece is screwed from the upside, while the other is screwed from the downside. This traditional method is done to disperse the tension and keep the screws tight.
Depending on the model, we use three-layer hinges, five-layer hinges, or seven-layer hinges.
Generally, three-layer hinges are the most popular and often used even to the largest size. Yet, BJ uses seven-layer hinges for the larger models to provide adequate strength. Our high quality domestic hinges enable you to open and close the temples smoothly.
We are not after cost-reduction or production-efficiency, but are focused solely on product quality.
