“The Silicone Gel Disc gives users greater comfort inside of the liner or socket. Prefabbed liners are not always a perfect fit—these discs can help a great deal. This Disc can be placed anywhere the user desires. Since it is composed of silicone, just like our liners, the tactifying nature of silicone allows it to “”stick”” without using adhesive. The user can place these in trouble spots that are causing them issues. Can be used with any liner. SKU Codes for the Silicone Gel Discs vary according to size and thickness. For example: • “”ESP-GD”” = Silicone Gel Disc, 4″” Diameter, 4 mm thick • “”ESP-GD2″” = Silicone Gel Disc, 4″” Diameter, 2 mm thick”
