Description

#4 invisible / concealed nylon closed-end zippers are heavier-weight than standard invisible zippers and measure 4.9mm across when zipped. These zippers do not separate at the bottom.

These are true invisible zippers - when the zipper is sewn into a garment, the zipper teeth do not show.

Looking for longer lengths? See our product listing for #4 invisible continuous zipper chain to create any length zipper you want!

Lead time is approx. 1-2 weeks. Zippers can also be made in custom colors (MOQs apply). Please complete our custom order form for a quote.

Excellent quality

best zipper prices on line!!

Quick shipping and best prices for invisible zippers around, with out
the fussy packaging that we all tear off and throw away! consistently
good values.

Perfect product.

I had no idea this company existed. I am so happy I have found it. They have every kind of zipper one could ever need for any kind of sewing project. And it appears they are located in Carlsbad, California, where I lived for a time, long ago.

Great Zippers

Great zippers that I've always been happy with. They always seem to have what I need in stock, or quickly available.

36" Invisible Zippers are the bomb!

I placed my first order for invisible zippers from Zipper Shipper recently, and I can't be any more pleased! The zipper order arrived quickly. I just inserted a 36" invisible zipper for the first time. Love it! The zipper went in effortlessly. It is invisible even with it being inserted next to piping. Highly recommend this company.

Great customer service and Great turnaround time!!

Unfortunately the zippers I purchased did not work but I have since communicated with the company via email and found out I ordered the wrong type of zipper...not size. Totally recommend this company!!!

Durable & Heavy Duty

Durable, heavy duty zipper I used on my husband's leather motercycle jacket. Worth paying the extra price to shorten it to 22 in. Made for perfect length.

Nice zippers, nice price, quick shipping

Now that so many sewing and craft stores are shutting down, it is good to find an online dealer who sells quality products at good prices!

#10 Molded Plastic Heavy Duty Separating (Jacket) Zipper

Great Replacement Zipper

The zipper on my daughter’s pink rain jacket broke, so rather than discard it and buy a new coat, we decided to try to be resourceful and replace the zipper. The tailor didn’t have one that even closely matched the color of the jacket, so we went online and found zippershipper.com! So glad we did because we found the perfect pink color, and the tailor sewed it in the jacket. It looks AWESOME!!! Thank you, zippershipper.com!!!

#5 Reverse Coil Separating (Jacket) Zipper

Outstanding product!!!

I ordered sport zippers for backpacks I make and they were the BEST I’ve ever purchased. The price was great, the delivery was fast, and I will continue to buy from this supplier.
Try them! You won’t be disappointed!!
