The trail of the man accused of shooting dead two Work and Income employees is into its third day.
Russell Tully wasn't present in court today. He lasted only a minute into the trial yesterday before being asked to leave for being disruptive.
Crown prosecutor Andrew McRae said on Wednesday that a cartridge with the distinctive sticker, "inX" had been found at the scene of the office shooting on September 1, 2014.
Mr McRae told the jury that Tully had used the stickers "to label his property".
Ashburton print-shop owner Clive Watson told the trial that a man in black clothing had come into the shop on August 13 or 14, 2014, and asked for the vinyl stickers to be made up.
He identified one of the stickers on a shotgun shell produced as an exhibit in court.
The one on the cartridge case "looks identical to what I made him", Mr Watson said.

Day three has seen evidence called from people who had dealings with Tully in the weeks prior to the shooting.
A man who was going about his deliveries in Ashburton on the morning of the WINZ shooting has recounted seeing a balaclava-clad gunman entering the office and the terror which followed.
Mr Sullivan says he witnessed several people flee the office before the gunman came out and made off on a bike.
"The Maori man came out and the others followed him and when the gunman came out the Maori man shouted out 'you bl***y b*****d, you blew her to bits' and that was when I realised things were really serious."
Mr Sullivan says he then rang 111.

Tully is standing trial for the murders of Peggy Turuhira Noble and Susan Leigh Cleveland and the attempted murder of Lindy Louise Curtis and Kim Elizabeth Adams, in a shotgun shooting at the Ashburton Work and Income NZ office in 2014.
He is also charged with setting a man trap – a steel wire stretched between two trees – and unlawful possession of two shotguns.
One shotgun is an exhibit in court, but alleged one used in the shootings has never been found.
Tully has no lawyer but is represented by two amicus curiae - friends of the court.
