### Size and materials

## Before you buy

- Check the 35mm size and square shape against your existing firebed and appliance requirements. Position replacement coals only as directed by the appliance manufacturer, keeping burners, ports and pilot areas unblocked. The listing describes the coals for compatible gas, LPG and certain decorative displays, while another description says most standard gas and electric fires. Compatibility is therefore not confirmed for every appliance.

## In the box

- Bag (Included)

## A good fit for

- Owners replacing small, square coals in a compatible fire who have checked the size and firebed layout.
- Buyers needing a 20-piece pack for a gas fire or a decorative display that specifies this coal type.

## Less suited to

- Buyers who have not checked whether 35mm square coals match their appliance's specified shape, dimensions and arrangement.
- Anyone seeking confirmation that these coals suit a particular fire model. The listing does not provide a model-specific compatibility list.

## Customer feedback

Aggregate ratings lean positive, with many five-star ratings, but the distribution also includes lower ratings. This offers only a broad indication of customer sentiment and does not identify specific strengths or problems. For a replacement-coal purchase, checking the stated size, shape and appliance layout is more directly useful than the overall rating.

## Frequently asked questions

### How many coals are included?
The listing states a pack quantity of 20.
### What size and shape are these replacement coals?
They are described as small square coals measuring 35mm. Compare them with your existing coals before ordering.
