Precautions on Zipper Use

Rough Slider Operation

Do not force the slider even if it doesn't move smoothly, or it may cause the elements to engage incorrectly.
Apply paraffin or wax on both the front and back surfaces of the elements, then move the slider back and forth to regain smooth operation.

Pulled Out Elements

Trying to forcibly close the zipper of an overfilled bag will cause element and tape breakage due to the excess load on the elements.
Reduce the burden by reducing the content of the bag and by bringing both sides of the chain close to each other before closing the zipper.

Fabric Caught in Slider

A slider may catch the fabric, hampering its operation.
Avoid forcing it to move or it will worsen the problem.
Slowly move the slider while pulling out the caught fabric.
Please allow enough room for the slider to move smoothly when sewing the zipper onto the fabric.

When Dressing / Undressing

Make sure to completely open the zipper when dressing / undressing.
Dressing / undressing without completely opening the zipper may damage the elements or the slider function.
When closing the zipper, the slider will move more smoothly if the hook & eye or the top button is fastened beforehand.

Proper Ironing Procedures

Not only garment fabrics, but also zippers have an appropriate ironing temperature according to their materials. Please adhere to the specified ironing temperature to maintain zipper quality.
Also, make sure to completely close the zipper, lay down the slider pull-tab in the regular position and place ironing fabric on the zipper.

(Pressure: 1.5kg, Applied for 10 sec.)
※ Direct ironing on elements or sliders may cause undesirable effects.

Proper Laundry Procedure

Make sure to completely close all the zippers when using the washing/drying machines. Incompletely closed zippers may become entangled with other items and result in element or slider damage or damage to the other item’s fabric.
Long or slim slider pull-tabs may become caught in the drum holes, causing breakage, so the use of a laundry net for these items is recommended.
After the drying process, do not operate the zipper until the garment temperature has cooled down to normal.
Strong alkaline detergent or chlorinated bleach may affect zipper operation. In such cases, use softeners, paraffin or wax to regain the smoothness.
Do not presoak garments with zippers in a washing solution, or it may cause significant damage.
