## Description

GPI - 4" x 6" - Bulk 1000 Count, 4 Mil Thick, Heavy Duty, Clear Plastic Reclosable Zip Bags, With Write-on White Block for Labeling, Strong & Durable Poly Baggies With Resealable Zipper Top Lock.

Review: Great Product - Fantastic! Then 4 Mil thick is perfect. I am storing buttons in them. The bags are easy to open and close. Sometime I have trouble opening them due to the design, but these are great. Very sturdy. I like that you can write on the bag to identify what is inside on one side of the bag and then clear on the other. Very happy with the purchase.
Review: Perfect size for trading cards - I'm using these to make bulk packs of mtg cards to sell & also to organize some by mechanics or type. These bags zip/seal well and are durable for reusing. They make homemade bulk card packs feel more professional due to their thickness & look more professional due to the good fit. Individual cards and small numbers of cards fit & look good. But up to 50 cards will fit & the snug fit makes the bags look custom-sized & professional. The label is a handy feature too but can be turned to the back if it's not needed. I expect these will be a staple for the bulk card side of our little hobby business and should work well for sports/baseball cards and Pokemon cards, in addition to the MTG cards that are my focus.

### ⭐⭐⭐⭐⭐ Do you appreciate good engineering, even in something as simple as a plastic Zip bag? I do.
*by K***R on April 23, 2026*

I've spent a lot of time sorting and inventorying all the parts and junk in my shop. I bought a package of these Zip bags to help me sort and store all my treasure (my wife calls it junk, but what does she know?) These bags are good. They are a heavy poly bag and don't easily puncture. I have a lot of electronic parts with sharp pointy bits and these bags have held up well. One side of the bag has a white writing surface which takes writing from a Sharpie marker well, so you can write a part description on the bag and easily read it because of the white background. I especially appreciate the Zip top of the bag. It is very important to let you know that the two edges of the top of the bag are OFFSET a bit so that it is EASY to open the two halves of the opening to unzip the bag. I hate having a Zip top bag where I can't separate the two edges to get it open! This bag is well designed and a joy to open! I have recently bought another 100 of these bags because I used all of them up. Good stuff.
