Thanks.I have a flatpack bookcase without all the necessary bookcase shelf support pegs. I have searched for them locally and online, without success. I include two photos. The ledge which supports the shelf has a raised circular edge which fits into a circular hole on the underside of the shelf. The peg is 5mm wide and approx 10.5mm long. The length of the whole thing including the peg is approx 38mm. Can you provide such shelf pegs or tell me where I could obtain them?
