Teachers, schools and users in educational settings and non-profit organisations pay the "edu" price, other web customers pay the "web" price.

Displayed prices are net of VAT but a running total of VAT payable on the goods in the basket is shown in the shopping basket summary at the top right of the header.
* The delivery cost in the shopping basket summary is an estimate assuming delivery to a UK mainland address and is updated once a delivery address is entered during checkout.
All weights and dimensions may vary as our instruments are all made by hand from natural materials.
