- PRODUCT MATERIAL: We use high-quality PVC material, which is 60% thicker than similar plastic zip envelop folders. Thick materials can extend the life of the product, increase the frequency of product use, and reduce waste. Transparent material, you can see the content directly, no need to repeatedly take out for confirmation, so it is convenient and fast. Completely waterproof, don't worry if you accidentally spill coffee on it.
- Could be confusing to organize if multiple colors are used.
