Larger seeds (squash types, beans, peas) can make it difficult to close as it's a popper shutting, but could be easily bound with a piece of twine.
Quality of work: Great for the price.
Material: Nice- should hold up fairly well.
Brought as a gift but would find it useful for me!
Good little ring binder with pockets so you can order the seeds as you prefer and nice brown paper envelopes to put the seeds in so they can stay in good condition. A really nice idea
