Wooden Bee Buttons Made from 4mm FSC CERTIFED MDF. The holes are 2.5mm in diameter if needed we can adjust the hole size. These wooden bee buttons are supplied blank ready to start your project as soon as they arrive no prep is needed for any of out blanks and embellishments. Tip: We find acrylic paints work really well. To glue to another surface any wood glue and even PVA works well as they are very light weight. If they are being used in an area where there might be damp we use a sealer to help protect it. We can supply these buttons in any size, if another size is needed please let us know via an email. All of our packing is either recyclable or we have recycled it from another company.
