Don,
I think that you are about spot on in terms of costs. But I would do things slightly differently. Omega Prices, £45 each. The need for a Fountain and Rollerball set is so infrequent that you are tying up your stock and restricting your buyers choice. I have sold sets twice in six years. If you do have pens that are, or could be pairs, then you may wish to add an incentive such as £80 for the pair. However, I think you will be surprised how few, if any pairs you sell. You may sell more pen and pencil sets and I think the sale price is a little undestated, the minimum should be £30.
On the issue of the commercially produced maple boxes, I would happily get the entire worlds stock and crush them, they are ghastly and expensive for what they are.
By way of explanation I'll relate a story of a craft fair I attended several years ago. There was one lady artist there exhibiting some acrylic paintings. Each was beautifully framed , but all hung unsold after three days and the lady was distraught, nobody was buying her goods. I offered her, when she asked, a bit of advice. Take the pictures out of the frames, which she did and next day sold over £400 worth. The frames were putting people off for two reasons, firstly they didnt want to be constrained with the choice of style and colour, it wouldnt have gone with 95% of the decor of the purchasers room, and secondly and more simply, it divided the purchasing decision into two parts, picture and frame. Despite the fact that the frame could be changed, it was an equally emotive decision, somewhat out of balance to the value of the goods but nevertheless another decision that could come in the way of a successful sale. Remove reasons for people not to buy.
Bin the box and get something utilitarian which looks respectable but is quite clearly cheap and not designed to be part of the product offering but part of the packaging, if you want to, offer the box as a separate add on, but dont display the pens in the boxes!
Hope that helps and best of luck.
