Spartan Industrial - Reclosable Zip Plastic Bags 4 Mil Heavy Duty (4" X 8")

These bags work well for the pencil packs that I make. The only thing wrong it that the end at the top where the opening is are the same length. They need to be a different length to make them easier to open.

I love these poly bags because they are thick and strong and stay closed good adhesive.

Perfect sized bags for keeping phone clean while working as a plasterer. Can still use phone.

Great bags for multi shipping and separation you could even fill them with air and seal with tape and use them as Packing bubbles
