Useful tools for smoothing sealing lines and caulking lines, which helps save sealant without masking tape when you apply it for sealing work.  

They are suitable for most types of sealant such as DIY crafts or floor silicone sealant, silicone, acrylic, resin, grout and more.

Maintenance: The caulking tools are reusable and good for any edge, corners, joints; 
Tidy up easily, just clean them with a damp cloth and convenient to apply next time. 

This model includes 2 sealant tools in different edges (filleted and chamfered). 
Each edge size is clearly marked:

• Chamfer 5mm
• Chamfer 9mm
• Chamfer 11mm
• Fillet 4mm
• Fillet 8mm
• Fillet 10mm

I've included f3d file for easy modifications if needed.

  (both work well with Arachne perimeter generator)
