This is an excellent honey filter. We use them exclusively for our honey straining. They are reusable, and we find that if we wash them after use, we can get many uses out of them. The are made of a durable plastic, and have a rolled edge around the top that enables it to fit securely in most 5-gallon pails. The are made in an FDA approved plant in the US. We find that the 400 micron filter size is ideal for our honey.
