These extruder discs are for the large extruder gun which you can find here. 
A lovely selection of whale or mermaid tails. If you are looking for whole mermaids, we do have a mermaid disc section for the large extruder.
The size of the embeds are:
 
Large straight tail 3.5cm high 2.5cm wide
Large wavy tail 3.6cm high 2.5cm wide
Small straight tail 2.2cm high 1.6cm wide
Small wavy tail 2.3cm high 1.6cm wide
 
The whale/mermaid tail discs discs are also available in the 23mm and 24mm ranges which will give a smaller embed size if required.
 
These discs will fit other large extruders, please just check the size if you have a different extruder. The diameter of the disc is 57mm.
 
The discs are only suitable for use with soap dough, not suitable for melt and pour soap.
 
There is a special postage rate available when buying scrapers and/or extruder discs only, as they can be sent 'large letter' size. Please select this option at the checkout. This postage option cannot be used if your order contains anything other than scrapers and extruder discs.
 
The discs are made from PLA, which is a plant-based material, and therefore environmentally friendly
 
These extruder discs will last you for many uses and help you create many beautiful soaps as long as you take care of them.

After use, wipe with a cloth to remove excess soap batter. I always find the discs easier to clean if you wipe and wash them soon after using.
Wash with warm soapy water, rinse and dry.
Your scrapers are made from PLA which is a temperature-sensitive thermoplastic polymer derived from renewable resources such as corn starch or sugar cane. PLA will start to deform and melt at around 60°C (140°F), please ensure your washing water is below this temperature
and never put your extruder discs in the dishwasher
