Perfect to have on standby for those larger items you might need to post or save such as copies of certificates. The seal is extremely strong and does not require additional tape when sending. These are packaged in thin film so once opened there is no easy way to keep them together but apart from that this this is a perfect product. Ideal thickness so that additional postage will not be added. Sufficiently durable to store documents longer-term. Perfect fit for A4 sheets and could probably take up to about 10 sheets per envelope.
