The Harry Potter Tour London has a huge amount of jewellery focusing on price points that range from reasonable (£4.95 for a slider charm) whilst the cheapest sterling silver slider charm - Hogwarts letter is a lot more detailed but expensive at £46.95. The silver plated slider charm range is the most affordable (there is also a Fantastic Beasts available range now as well). Made by Carat London some charms, slider bracelets, slider necklaces and HP jewellery are available on their website whilst some others are HP exclusives and only available instore. The Hogwarts in the Snow slider charm and charm necklace (£4.95 and £8.95) are the only charms available on the HP Tour online shop and are also instore. Some of the charms and bracelets are also available at the platform9/34 webshop which is linked to the Kings Cross Harry Potter shop. The HP Tour webshop focuses on the higher end sterling silver slider charms (£50 and over) which are 3D and ofcourse are much more detailed than the £4.95 range. The Carat shop also does starter packs that are slightly cheaper with 4 charms in them (£15.95), several spell divider charms (£8) or a bracelet with 4 charms for £19.95.

The silver plated slider charms are flat and fit most slider charm bracelets and necklaces. The enamel detailing is quite detailed and the charms themselves are well made. The bracelet comes in three sizes s (18cm), m (19cm), l (20cm) (£5.95) and is available in silver plate or a black cord. The necklace is 44 cm, costs £8.95 and is silver plated. They all have a branded clasp. The fantastic beasts range has a brownish corded bracelet which ties in with the colour scheme for that range.
I bought the ones pictured for my mum for Christmas. She can add to her collection everytime she goes to the Tour as they are one of the most reasonably priced items in the HP shop. She has arthritis in her hands and whilst she didn't find it hard to slid the charms onto the bracelet she did find it difficult to fasten.
