TKHP 100pcs/lot Clear Thick Heavy-Duty Zip Lock Storage Bag
They are 2 millimeters thick and feel heavy duty in hand.
The quality of the plastic is great, and the resealable strip has a good snap. They are fully transparent, so that contents are clearly visible; and the zipper works perfectly.
Use them for screws and small parts in the moving, for snacks, desk supplies and a myriad of other things.
They also seem to zip shut much easier and are easier to aline the zipper. However, when opening these bags, because the lock is stronger, you must be careful not to pull to hard as to not rip the plastice side seam.
These have no offensive smell and are thick enough that pointy bits don't tear through. The zipper portion is easy to close.
