The description you provided refers to an RFID (Radio Frequency Identification) tag with the following characteristics:

• Material: ABS (Acrylonitrile Butadiene Styrene), which is a durable plastic commonly used for tags due to its resistance to impact and weathering.
• Diameter: 25mm, which indicates the size of the RFID tag, typically referring to its round shape.
• No Hole: This suggests that the tag does not have a hole for attachment, meaning it may be designed for direct adhesion to surfaces or for use in certain mounting systems.
• LF (Low Frequency): Refers to the frequency range of the RFID tag. Low Frequency RFID operates typically at 125 kHz or 134.2 kHz, commonly used in applications like animal identification, access control, and asset tracking.

This tag would typically be used for identification and tracking purposes, and the absence of a hole means it could be used where direct attachment or embedding in a product is desired, such as in security, inventory, or animal tracking applications.
