To Lisato, I am listing these items together. Thank you. I am relisting these items with a price change due to the Mercari market. I will omit the product description as it is also listed elsewhere. The reaction to the microchip has been confirmed in photo 4. The purchase date was around the spring of 2021. It was used for about a year and then stored. There may be minor scratches and stains that are not noticeable. Also, there is some discoloration due to sun exposure. Please refrain from purchasing if you are concerned. The main unit and tag are registered, so it can be used immediately when batteries are inserted. Another item, a mat and one without a microchip, is also on sale at a slightly lower price. I am relisting these items with a price change due to the Mercari market. This product does not include a mat or microchip. Please purchase a separate microchip or use it with a cat that already has a microchip. The reaction to another microchip has been confirmed in photo 4. The purchase date was around the spring of 2021. It was used for about a year and then stored. The movement felt slightly jerky, but it was within a range that did not interfere with use. There are minor scratches and stains that are not noticeable, and discoloration due to sun exposure. Please refrain from purchasing if you are concerned. The plate with dividers is unused. I will leave the batteries in from the operation check. Another item, one with a microchip, is also on sale.
