The product is excellent and very easy to work with. My only negative was that it took over a week to ship my product out. My business depends on these and waiting too long stops my business.

Excellent product!
Used them to plug some 20 tapes. The only issue is sometimes when the original tab is taken out there is some plastic still in place. Just a fast trim with a cutter and the tabs fit in 100%.
So MUCH better than tape!

Looks great, good colors. Crisp printing and great finish

Needed to be manually arranged in photoshop, but came out great. Really sticky, I don't think they're going to come off anytime soon

The jackets came out amazing!! The customer service from Ming and Steven is exceptional!! Would recommend to anyone!

These are high quality jackets. Not always easy to track down 10" versions of these. Great buy.

These are pricey, but are great to ship 2 or more LPs. It would be nice to have a mailer for single LPs, one that would not take as long to assemble.

The tape arrived in perfect condition. I used the 440Hz tone with a guitar tuner to check my tape deck speed. Also by using an oscilloscope I was able to measure the delay between the left and right stereo channels. The amplitudes of the left and right channels were different by about 2dB but I attributed that to difference in alignment of the test tape recorder and my cassette deck. I decided to leave my head alignment alone. This is a very useful product and I highly recommend it.

Good production, and great pricing.

Good pricing.

These mailers are excellent for shipping cds. They're durable and easy to label. The only drawback is that they cost slightly more in postage for shipping with Canada Post because of the weight of the mailer.
I'd order these again

the shell work well and the best great price

Customer support was super helpful and quick to respond. The obistrips are really well made, sturdy and fit the tapes perfectly! Shipped to CO. Well packed and included a tracking number.

I was hoping to like these but there's something weird about the build. I was buying bulk polyethylene inner sleeves similar to these, elsewhere but they stopped carrying them, so I tried these ones.

Compared to the others I've used, it almost seems like the ones I got are inside-out.. the smooth, silky texture is on the outside and the shiny, slightly gummy texture is on the inside. It creates some friction with the disc when inserting and removing.

Perhaps I got a bad batch or they're meant to be this way, but as I said, I'm comparing to similar sleeves I bought elsewhere and the textures on these seem off to me. Don't think I would buy again.

very good quality and a really good turnaround, from ordering to recieving here in ireland took only 5 day's, i'm glad to find a source of new cassette's to copy some of my 40 year old tapes to

good solid cases unlike maxell's brittle one's

It is difficult to find mailers that are the ideal size for shipping vinyl LP records. After much searching, I found this product and it is great. Good price for the product.

My opinion matters? Lil ol me? Well hot rotterdam! 5 stars, this place did NOT mess up my order and thats a win for everyone in this transaction. I recommend!

100% satisfied! I will buy again. Good quality of inner sleeves

Great product! Aside from that, really the great thing about duplication.ca are the folks that work there. I’m lucky enough to live close and when it was still ok to visit the store it was always a pleasure to go in and talk audio stuff. Great place!

The selection I got look great! Going through the recording process now, they sound great too. Thanks Duplication!

Very fast shipping great product great service. thank you.

These are awesome! The construction is quality and consistent. The corners of the case are slightly rounded and sleek and very user friendly . I packaged a variety of different cassette shell colors and styles in them and they all looked great especially clear, yellow, black and white. The shade of green is a unique fluorescent with an almost iridescent shine. They really pop under UV lights as well. These cases make you want to touch them and explore what’s inside. I highly recommend them.
