These are my absolute favorite bags by Clear Bags– high quality, food safe, crystal clear heat seal bags are perfect for packaging your treats and creating an air tight seal. Bags have a security seam at the bottom and back, ensuring that your seals are air-leak free. Superior to bags with no seams since this does not allow for sneaky air-hole leaks along the bottom and sides of many other types of cello bags. Available sizes are 3×5, 3×9, 4×6, and 5×7 inches (flat, no gusset). Each set comes with 100 pcs. Scroll through my photos to see how I use these bags!
