There are 2 main type of vinyl stickers:
Heat Transfer Vinyl: These are also called iron one labels, specialised vinyl that is activated by heat (of a particular temperature) applied to fabric items e.g. clothing & apparel, canvas bags, school bags. These are great for personalising items made of fabric material where you can send your image for printing and cutting and apply yourself or purchase the finished clothing items with the customised vinyl already applied.
Vinyl waterproof adhesive stickers for application of items like glass, plastic, metal, perspex and similar items. You can send your customised text and preferred colour and size which is quoted accordingly then apply it to mugs, flasks, bottles, keyrings etc. You can also send images for printing and apply these to sign boards or glass doors etc.
